built-in shelf


sgml-dtds is a built-in shelf used to store compiled SGML DTDs. These items are typically created and used as follows:

  • Compiling a DTD (using creating with either document or subdocument) assigns an item of the shelf to be the compiled DTD. If the item did not previously exist, it is created.
  • Parsing an instance or partial instance (instance or with document-element) uses an item of the sgml-dtds shelf. An item of this shelf can be used any number of times. Items can even be used simultaneously for nested do sgml-parse actions.

Apart from this special syntactic support, the sgml-dtds shelf behaves like an ordinary shelf of type sgml-dtd.
