Excerpts from the SGML Standard
From ISO 8879:1986, Information Processing
Text and Office Systems Standard
Generalized Markup Language (SGML):
- 4.51 conforming SGML document
- An SGML document that complies with all provisions of this
International Standard.
- 4.102 document type
- A class of documents having similar characteristics; for example,
journal, article, technical manual, or memo.
- 4.105 document (type) definition
- Rules, determined by an application, that apply SGML to the
markup of documents of a particular type. A document type definition
includes a formal specification, expressed in a document type
delcaration, of the element types, element relationships and
attributes, and references that can be represented by markup. It
thereby defines the vocabulary of the markup for which SGML defines
the syntax.
