Completed Work
W3C Recommendations have
been reviewed by W3C Members, by software developers, and by other
W3C groups and interested parties, and are endorsed by the
Director as Web Standards. Learn more about the W3C Recommendation
Track.
Group Notes are not standards and do not
have the same level of W3C endorsement.

XML Schema: Datatypes is part 2 of the specification of the XML
Schema language. It defines facilities for defining datatypes to be used
in XML Schemas as well as other XML specifications.
The datatype language, which is itself represented in
XML 1.0, provides a superset of the capabilities found in XML 1.0
document type definitions (DTDs) for specifying datatypes on elements
and attributes.

XML Schema 1.0 did not anticipate new versions of XML, and mandated
XML 1.0 documents as the starting point for schema-validity
assessment. Some users and specifications would like to use XML
Schema processors which process XML 1.1 documents, and some
implementors of XML Schema processors would like to provide XML 1.1
support.
This Note suggests an implementation strategy for implementors to
adopt to enable users and specifications to get such support in a
consistent way. All aspects of XML Schema which are liable to
re-interpretation as a result of changes in XML 1.1 are discussed.
An implementation of schema-validity assessment employing such a
strategy is strictly speaking non-conformant to the current version
of the XML Schema specification. The XML Schema WG none-the-less
believes that interoperability will best be served by such
non-conformant processors being made available to users, until such
time as a subsequent version of XML Schema addressing this issue
normatively is approved.

This
document specifies the XML Schema Definition Language,
which offers facilities for describing the structure and constraining the contents
of XML documents, including those which
exploit the XML Namespace facility. The schema language, which is itself
represented
in an XML vocabulary and uses
namespaces, substantially reconstructs and considerably
extends the capabilities found in XML
document type definitions (DTDs). This specification depends on
XML Schema Definition Language 1.1 Part 2: Datatypes.
