SGML Keyword Syntactic Literals

A keyword is a parameter that is a reserved name--a syntactic literal. Keywords appear in productions as quoted strings of symbols or words in all capitals, i.e., "SYSTEM". They have an identification role in the productions. In parameters where either a keyword or a name defined by an application could be specified, the keyword is always preceded by the reserved name indicator rni #. Those keywords below are preceded by #, i.e. "#DEFAULT".

Each keyword used in any production appears in sorted order, ignoring any #. Each syntactic variable defined in each production in which a syntactic literal is used is shown by a triple:

syntactic variable name[production number] {locator}

Syntactic variable name is that defined in the SGML Syntax Summary.[production number] is linked to the definition therein of that syntactic variable. The {subclause, page:line} locator refers to the subclause from ISO 8879, repeated in both the Syntax Summary, and in Goldfarb, The SGML Handbook; to which also the page:line refer.

Note the occasional multiple occurrences of the syntactic literal in the definitions of different syntactic variables. These may have different semantics in each context.
