xml:id Is a W3C Recommendation
The World Wide Web Consortium
today released xml:id Version
1.0 as a W3C Recommendation. The specification defines an attribute
name, xml:id
, that can always be treated as an identifier
and hence can always be recognized, without fetching external
resources, and without relying on an internal subset. The
Recommendation is the latest deliverable of the XML Core Working Group, part of the W3C
XML Activity.
