Modify an existing string content type by adjusting its constraints such as length or
pattern to better fit your data requirements.
About this task
You can create a custom string type by starting with an existing one and changing its
rules, such as setting a maximum length or a specific pattern. Instead of using the same type for
every string or list of strings, this method applies more specific rules that match your
requirements. When you customize a type, you are creating a new content type. These rules called
constraining facets, follow the standards that are defined in the XML schema.
Procedure
- Select the variable where you want to apply the customized content type, then click the
Edit icon
- Click the Content type drop-down menu and choose the content type
that you want to customize.
The constraining facet fields appear in the content type
list.
- Enter the values for the constraining facets you want to apply, then click
Save.
Note: The available constraining facets depend on the primitive type of the selected content type.
Primitive types are basic data types like string, number, or Boolean. For example, if the primitive
type is
string, you see facets such as
Enumeration,
Length,
Minimum Length,
Maximum Length,
Whitespace, and
Pattern. For more information about primitive
types, see
