-Subset
of [SGML].
+An [Acronym] (yet another [TLA]) for e__X__tensible __M__arkup __L__anguage, a marginally human read-/editable MarkupLanguage which is a simplified decendant
of [SGML]. The [W3C] maintains the [XML] standard
.
-E__x__tensible __M__arkup __L__anguage
+[SGML] was an extremely comprehensive standard for which hardly a single fully compliant parser was ever written. Many of its features, even implemented ones, are hardly used. On the other hand, it lacks various useful features. [XML] was designed to address these shortcomings while reducing the language specification to a small set of rules in order to be easily and consistently parsable. It lacks features such as [CONCUR] but adds others such as [NameSpace]s (as good an idea in a MarkupLanguage as they are in a ProgrammingLanguage).
-A
language for marking up information
, usually used
for interchange between programs and for file formats. Marginally human readable and editable
, but mostly designed
for computer generation
and reading
.
+[XML] is specialised using a [DTD], an XML[Schema], or a [RelaxNG] schema to describe the structure of data within a [XML] document. Each specialisation is actually a new
language for marking up a particular type of data. Thus DocBook is a specialisation for marking up the text of books
, [XHTML] is a specialisation
for marking up web pages
, [MathML] is a specialisation
for marking up mathematical equations, tables
and formulae and [XSLT] is a specialisation for marking up a programming language (a functional programming language expressed in [XML])
.
