SGML Syntax Summary

This document shows the syntactic productions of SGML, with hyperlinks to simplify their study. The clauses containing productions appear as they are in the SGML standard, to give context for those productions.

The extensive hyperlinks show where the syntactic variables and other tokens used in productions are defined, and where the defined syntactic variables are used in other productions. Locators provide {clause and page:line} references, to facilitate use with either the ISO 8879 standard or the The SGML Handbook.

1 Scope

The syntax of SGML productions, with hyperlinks to where productions are defined and where in the definitions of other productions they are used.

2 Field of Application

The allowable syntax for describing markup languages that will permit proper SGML parsing and validation, SGML application designs, and application document markup consonant with such designs.

3 References

The SGML Handbook includes and amplifies the ISO 8879-1986(E) SGML standard.

See the DSSSL Syntax Summary Index for the related Document Style Semantics and Specification Language, ISO/IEC 10179:1996.

4 Definitions

Concept clarification for technical terms and phrases.

5 Notation

Syntactic productions in order of production numbers appear as:

[prod. no.] defined syntactic variable name =

definition, one line per syntactic token, possibly with metacharacters

reference {clause, page:line}, used in: list of syntactic variables[prod.no] where this production is used

The metacharacter symbols used with syntactic tokens indicate their precedence:

surrounding parentheses "(...)", before

selection suffix, one of optional "?", optional and repeatable "*", repeatable "+", or required--no suffix, before

ordering infix, one of sequence ",", alternative "|", or all in any order "&".

Five forms of token appear in definitions:

syntactic variable token, with a link to the production where that syntactic variable is defined
delimiter role, character representations from the reference delimiter set, such as stagc for start-tag close
keyword syntactic literal, such as "CDATA"
terminal constant, such as Digit, lines end with usual characters
terminal variable, such as RE, lines end with (ASCII position) ASCII-name
