D Changes since version 1.0

This version incorporates the errata to version 1.0 as of 6 December 2002 [errata10] . There are two further substantive changes:

• A mechanism is provided for undeclaring prefixes;

• Namespace names are IRIs, rather than URIs.

There are several editorial changes, including a number of terminology changes and additions intended to produce greater consistency. The non-normative appendix "The Internal Structure of XML Namespaces" has been removed.
