IETF XML Element ID Registry

Very important and useful. I only wish that there was a formal effort underway to unify blogging standards. But as I promised, more on that when I get mentally coherent on the subtleties of the subject.

This document creates an IANA maintained registry of XML element identifiers so that document authors and implementors have a well maintained and authoritative location for their XML elements. As part of this standard, the IANA will maintain

• the public representation of the document,
  
• the URI for the elements if one is provided at the time of registration,
  
• a registry of Public Identifiers as URIs.
