| XML/SGML parsing: built-in shelves | |||||||||
Certain built-in stream and integer shelves exist only to support SGML and XML parsing activity. These shelves must not be accessed outside SGML or XML parsing.
The following stream and integer built-in shelves must not be accessed in process, process-start, or process-end rules:
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
document-end rules if errors occurred before this information could be determined
