'Base' SGML is defined by the ISO 8879 (?), and isn't by itself very
useful for text markup. It doesn't contain any markup commands - those
are provided by separate document type definitions (DTDs).

The DTD used by your encyclopeadia should be declared by a <!DOCUMENT
name ...> clause close to the beginning of the file. The file
specified by this clause is where you're likely to find the definition
of those cross reference commands.

Hope this is of any help,
