Message Sets: Global attribute logical properties

The logical properties of a global attribute.

Property	Type	Meaning
Name	String	Specify a name for the object when you create it. Names can consist of alphanumeric characters, including the letters A through Z, a through z, and the digits 0 through 9. They might also include the following punctuation characters; `-` the hyphen `_` the underscore `.` the period Names can start only with a letter or the underscore character, and not with a number, hyphen, or period. Names that begin with `xml`, or any variant of these characters (for example `XmL`), are reserved by the XML standards specification. Further details of naming conventions and allowable characters can be found in the Extensible Markup Language (XML) specification that can be found on the World Wide Web Consortium (W3C) Web site.
Type	Enumerated type	The Type property constrains the type of data that can be present in the object. Select from the following options: `int` `string` `Boolean` `hexBinary` `dateTime` `date` `time` `decimal` `float` `(More...)` `(New Simple Type)` `(New Complex Type)` If you select (More...), the Type Selection wizard starts. In this wizard, you can select any of the available types. If you select (New Simple Type), the New Simple Type wizard starts. In this wizard, you can create an Anonymous simple type that is based on an existing type. This type can be created locally or globally. If you select (New Complex Type), the New Complex Type wizard starts. In this wizard, you can create an Anonymous complex type, which can be derived from an existing base type. This type can be created locally or globally. For further information about these types, and examples of their use, see the XML Schema Part 0: Primer. This document is available on the World Wide Web Consortium (W3C) Web site.
Namespace	Enumerated type	Namespaces are a simple method for qualifying element and attribute names by associating them with namespaces identified by URI references. If <no target namespace> is displayed, a namespace has not been set for this object. If the property is inactive, the message set has not been configured to support namespaces. Where the property is active, namespaces that are available for selection are displayed in the drop-down list.

Property

Type

Meaning

Name

String

Specify a name for the object when you create it.

Names can consist of alphanumeric characters, including the letters A through Z, a through z, and the digits 0 through 9.

They might also include the following punctuation characters;

- the hyphen
_ the underscore
. the period

Names can start only with a letter or the underscore character, and not with a number, hyphen, or period.

Names that begin with xml, or any variant of these characters (for example XmL), are reserved by the XML standards specification.

Further details of naming conventions and allowable characters can be found in the Extensible Markup Language (XML) specification that can be found on the World Wide Web Consortium (W3C) Web site.

Type

Enumerated type

The Type property constrains the type of data that can be present in the object.

Select from the following options:

int
string
Boolean
hexBinary
dateTime
date
time
decimal
float
(More...)
(New Simple Type)
(New Complex Type)

If you select (More...), the Type Selection wizard starts. In this wizard, you can select any of the available types.

If you select (New Simple Type), the New Simple Type wizard starts. In this wizard, you can create an Anonymous simple type that is based on an existing type. This type can be created locally or globally.

If you select (New Complex Type), the New Complex Type wizard starts. In this wizard, you can create an Anonymous complex type, which can be derived from an existing base type. This type can be created locally or globally.

For further information about these types, and examples of their use, see the XML Schema Part 0: Primer. This document is available on the World Wide Web Consortium (W3C) Web site.

Namespace

Enumerated type

Namespaces are a simple method for qualifying element and attribute names by associating them with namespaces identified by URI references.

If <no target namespace> is displayed, a namespace has not been set for this object.

If the property is inactive, the message set has not been configured to support namespaces.

Where the property is active, namespaces that are available for selection are displayed in the drop-down list.

Value

The Value properties are used with the Usage property in an Attribute Reference or a Local Attribute.

Property	Type	Meaning
Default	Button and String	This property provides the default value for an element or attribute. XMLNSC domain When parsing with validation enabled, default values are applied to missing attributes and empty elements as required by the XML Schema 1.0 specification. When writing, elements or attributes that are missing from the message tree are not automatically added to the output XML bit stream, even if they have default values. If missing elements or attributes are required, the message tree can be serialized and then re-parsed with validation enabled. MRM (CWF and TDS physical formats) When writing a fixed-length portion of a message (CWF or fixed-length TDS), if an attribute or element is missing from the message tree, the default value is inserted into the bit stream so that the message structure is preserved. MRM (XML physical format) No support for default values Other domains No support for default values.
Fixed	Button and String	This property provides the fixed value for an element or attribute. XMLNSC domain When parsing with validation enabled, if an attribute or element is present, the value is validated against the fixed value. If the values are not equal, a validation error is signalled. Also, when parsing with validation enabled, fixed values are applied to missing attributes and empty elements as required by the XML Schema 1.0 specification. When writing, elements or attributes that are missing from the message tree are not automatically added to the output XML bit stream, even if a fixed value has been specified. If missing elements or attributes are required, the message tree can be serialized and then re-parsed with validation enabled. MRM (CWF and TDS physical formats) When writing a fixed-length portion of a message (CWF or fixed-length TDS), if an attribute or element is missing from the message tree, the fixed value is inserted into the bit stream so that the message structure is preserved. MRM (XML physical format) No support for fixed values Other domains No support for fixed values.
Interpret Value As	Enumerated type	Specify if values stored within this object must be interpreted as having significance for the parser and, if so, the type of interpretation that must occur. Select one of the following options: None This value is the default value, and indicates that the element or attribute does not have a key value associated with it. MessageSetIdentity. Specifies that the value of the element or attribute corresponds to the identifier, name, or alias (in that priority order) that is associated with the message set where all subsequent embedded messages that are descendents of the enclosing message are defined. This value remains in force unless a new element or attribute MessageSetIdentity field is encountered which resets the MessageSetIdentity value. MessageIdentity. Specifies that the value of the element or attribute corresponds to the name or alias (in that priority order) that is associated with a message, and acts as an identifier for subsequent embedded messages which are the immediate children of the enclosing message. This identity applies until a new element or attribute MessageIdentity field is encountered at the same level in the tree. The embedded message can be defined in either the current message set, or in a message set identified by using a MessageSetIdentity. Note: This property is applicable only when the type of the object is derived from xsd:string.

Default

Button and String

This property provides the default value for an element or attribute.

XMLNSC domain: When parsing with validation enabled, default values are applied to missing attributes and empty elements as required by the XML Schema 1.0 specification. When writing, elements or attributes that are missing from the message tree are not automatically added to the output XML bit stream, even if they have default values. If missing elements or attributes are required, the message tree can be serialized and then re-parsed with validation enabled.
MRM (CWF and TDS physical formats): When writing a fixed-length portion of a message (CWF or fixed-length TDS), if an attribute or element is missing from the message tree, the default value is inserted into the bit stream so that the message structure is preserved.
MRM (XML physical format): No support for default values
Other domains: No support for default values.

Fixed

Button and String

This property provides the fixed value for an element or attribute.

XMLNSC domain: When parsing with validation enabled, if an attribute or element is present, the value is validated against the fixed value. If the values are not equal, a validation error is signalled. Also, when parsing with validation enabled, fixed values are applied to missing attributes and empty elements as required by the XML Schema 1.0 specification. When writing, elements or attributes that are missing from the message tree are not automatically added to the output XML bit stream, even if a fixed value has been specified.

MRM (XML physical format): No support for fixed values
Other domains: No support for fixed values.

Interpret Value As

Enumerated type

Specify if values stored within this object must be interpreted as having significance for the parser and, if so, the type of interpretation that must occur.

Select one of the following options:

None This value is the default value, and indicates that the element or attribute does not have a key value associated with it.
MessageSetIdentity. Specifies that the value of the element or attribute corresponds to the identifier, name, or alias (in that priority order) that is associated with the message set where all subsequent embedded messages that are descendents of the enclosing message are defined. This value remains in force unless a new element or attribute MessageSetIdentity field is encountered which resets the MessageSetIdentity value.
MessageIdentity. Specifies that the value of the element or attribute corresponds to the name or alias (in that priority order) that is associated with a message, and acts as an identifier for subsequent embedded messages which are the immediate children of the enclosing message. This identity applies until a new element or attribute MessageIdentity field is encountered at the same level in the tree. The embedded message can be defined in either the current message set, or in a message set identified by using a MessageSetIdentity.
