external-text-entity #document
A rule that establishes a framework for explicitly providing an entire "SGML document entity" to the SGML parser.
If a context-translate or up-translate program contains an external-text-entity #document rule, there is no automatic submit of either the files named on the command line or by #process-input. The external-text-entity #document rule is used for processing the SGML document entity. If it needs to access files named on the command line, it can examine the #command line-names built-in stream.
The external-text-entity #document rule is different from other kinds of external-text-entity rules:
#document can't be mixed with entity names or with the keywords #dtd, #charset, #capacity, or #syntax in the header of the rule.
external-text-entity #document rules in the program, one must be selected to provide the SGML document. (Having more than one or none that is selectable causes an error.)
external-text-entity #document rule must not contain any find-start or find-end rules, because there is no reason for them ever to be performed.
external-text-entity #document rule only applies to the main SGML document, and not to documents whose parsing was initiated by a do sgml-parse. Thus, the #current-output inherited by an external-text-entity #document rule is always the #sgml stream created by context-translate, down-translate, or up-translate.
external-text-entity #document rule because such a text entity does not have a name.
