XML element name and attribute name formation
In the XML documents that are generated from identifier-2, the XML element names and attribute names are obtained from the NAME phrase if specified; otherwise they are derived from the names of the data item specified by identifier-2 and from any eligible data-names that are subordinate to identifier-2.
The formation of XML element name and attribute name is as follows:
- The exact mixed-case spelling of data-names from the data description entry is retained. The spellings from any references to data items (for example, in an OCCURS DEPENDING ON clause) are not used.
- Data-names that start with a digit are prefixed by an underscore. For example, the data-name '3D' becomes XML tag or attribute name '_3D'.
- Data-names that start with the characters 'xml', in any combination of uppercase and lowercase, are prefixed by an underscore. For example, the data-name 'Xml' becomes XML tag or attribute name '_Xml'.
DBCS data-names, when translated to Unicode, must be legal as names in the XML specification, version 1.0. For details about the XML specification, see XML specification.
