SGML Terminal Constants

Copyright © 1996 Harvey Bingham

The terminal constants represent character classes common to all SGML documents. The terminal constants are described in ISO 8879-1986,

Figure 1 Character Classes: Abstract Syntax {9.2.1, 345:0}

Each production in which a terminal variable is used is shown by a triple:

syntactic variable name {locator}
[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.

A terminal constant appears in a production as a bold string with mixed case, such as LC Letter.
