set compilesgml= { on | off}

This command states whether a document type is SGML or XML. When Arbortext Architect loads a document type, it checks for the XML PI at the beginning of the document type. If the XML PI is present, the document type is XML, and Arbortext Architect automatically sets compilesgml to off. If the XML PI is absent, the document type is SGML, and Arbortext Architect automatically sets compilesgml to on.

The value of compilesgml also determines whether the SGML Application or XML Application option is selected on the following menus:

If the you change the application value on these menus, the compilesgml value is also changed.

The default value of compilesgml is on.
