Extensible HyperText Markup Language (XHTML) is a reformulation of HTML 4.0
as an application of XML 1.0. XHTML 1.0 specifies three DTDs that correspond
to the HTML 4.0 DTDs, along with an XML namespace which is identified by a
unique URI. XHTML 1.0 is promised to be the basis for a family of future
document types which extend and subset HTML.
