Sgml in a sentence

A report on an early implementation of a parser for basic SGML, the Amsterdam SGML Parser, citation notes the DTD-grammar in SGML must conform to a notion of unambiguity which closely resembles the LL(1) conditions and specifies various differences.

Applications Document markup languages defined using SGML are called "applications" by the standard; many pre-XML SGML applications were proprietary property of the organizations which developed them, and thus unavailable in the World Wide Web.

A tag-valid SGML document is defined by the standard as An SGML document, all of whose document instances are fully tagged.

A type-valid SGML document is defined by the standard as An SGML document in which, for each document instance, there is an associated document type declaration (DTD) to whose DTD that instance conforms.

DocBook SGML and LinuxDoc are better examples, as they were used almost exclusively with actual SGML tools.

In addition to disabling many SGML options present in the reference syntax (such as omitting tags and nested subdocuments) XML adds a number of additional restrictions on the kinds of SGML syntax.

Markup minimization SGML has features for reducing the number of characters required to mark up a document, which must be enabled in the SGML Declaration.

SGML did this by a relatively simple default reference concrete syntax augmented with a large number of optional features that could be enabled in the SGML Declaration.

SGML provides apparatus for linking to and annotating external non-SGML entities.

SGML, which was based on both GML and GenCode, was developed by Goldfarb in 1974. citation Goldfarb eventually became chair of the SGML committee.

XML adoption was helped because every XML document can be written in such a way that it is also an SGML document, and existing SGML users and software could switch to XML fairly easily.

Although full SGML allows implicit markup and some other kinds of tags, the XML specification (s4.3.1) states: Each XML document has both a logical and a physical structure.

An SGML document may be composed from many entities (discrete pieces of text).

Because each processor's System Declaration can be compared to the document's SGML Declaration it is always possible to know whether a document is supported by a particular processor.

DocBook 4.x formats can be SGML or XML, but the XML version does not have its own namespace.

For compatibility with SGML, the string "--" (double-hyphen) is not allowed inside comments; citation Section "Comments" this means comments cannot be nested.

For example, despite enabling SGML shortened tag forms, XML does not allow unclosed start or end tags.

For example, SGML made end tags (or start-tags, or even both) optional in certain contexts, because its developers thought markup would be done manually by overworked support staff who would appreciate saving keystrokes.

Full SGML is rarely found or used in new projects.

However this behaviour is application-specific, and requires that the application maintains a catalog of known URNs to resolve them into the notations that have been parsed in a standard SGML or XML parser.
