XML/SGML parsing: built-in shelves |
Certain built-in stream and integer shelves exist only to support SGML and XML parsing activity. The following built-shelves may only be accessed within SGML or XML parsing:
Whether #appinfo
and #doctype
actually provide information depends on the state of the
parsing. They provide information only if the document being parsed, or the DTD being used to parse it, provides
the information. In particular, this means they are never attached in:
document-start
rules,
do sgml-parse
or do xml-parse
actions prior to a %c
operator or
suppress
action, unless a precompiled DTD is used,
do sgml-parse
or do xml-parse
actions after the %c
operator or
suppress
action, and
document-end
rules if errors occurred before this information could be determined.
