Generating for XML
You can generate an XML DTD file from an OOM.
A DTD file provides an overall structure for an XML file. The DTD file can
be used as a standard for validating data in XML files or for exchanging data
in XML format.
You can generate an XML DTD in one of the following format types:
XML file format Description
XML - DTD Used for standard DTD specification. Each class is
generated as an ELEMENT, with its attributes as sub-
elements. Each Attribute is generated as a PCDATA
ELEMENT
XML - Schema Used for XML Schema specifications: Each class is
generated as a <type>. Each attribute is generated as an
<element>
XML - Data Used for XML Data specification. Mapping is defined by
the XOL specification
Navigable associations are migrated and generated as attributes, although
they do have their own definition in the XOL file. You can specify a separate
definition for a composition association.
Other objects such a interfaces, operations, and inheritance links are not
included in the generated file.
