Description-en: Emacs major mode for editing SGML documents
PSGML is a major mode for the editor Emacs used for editing SGML
documents. It contains a simple SGML parser and can work with any
DTD. (The most popular nowadays are the HTML DTDs. This package
turns your emacs into the one of most powerful HTML editors and will
be ultimately flexible as well, since you could upgrade your editor
by just installing new DTDs). Functions provided includes menus and
commands for inserting tags with only the contextually valid tags,
identification of structural errors, editing of attribute values in a
separate window with information about types and defaults, and
structure based editing.
.
Since psgml parses the DTD to allow you to edit SGML documents, you do
need to have the DTDs installed in order to use psgml. Since psgml
installs itself as an HTML mode in Emacs, it depends on sgml-data. Some
other packages which also provide SGML DTDs are suggested, like
debiandoc-sgml and linuxdoc-sgml.
.
SGML, a language for encoding the structure of a document, is an ISO
standard: ISO 8879:1986 "Information processing - Text and office
systems - Standard Generalized Markup Language (SGML)".
.
Psgml is a standard package for XEmacs, and thus this package does not
install itself for XEmacsen.
.
The official home page has not been updated since 2005. The latest version
of this package was built from an unofficial version at
