This document lists implementation
feedback about XML 1.1 implementations known by the XML Core Working Group
at this time.
There is an XML 1.1 specific test suite--along with other
XML tests--available via the XML Test
Suite page.
RXP
The latest test version
of RXP (1.4.0pre9) supports XML 1.1 and passes all the tests in the XML 1.1
test suite. It incorporates code from Martin Duerst to optionally check for
Unicode character normalization.
Xerces-C++ version 2.3.0
includes "a full experimental implementation of XML 1.1, W3C Candidate Recommendation
of October 15, 2002 (Note: section 2.13 [character] Normalization Checking
has not been implemented)."
Xerces2 Java version 2.4.0 "is now able to parse
documents written according to the XML 1.1 Candidate Recommendation, except
that it does not yet provide an option to enable [character] normalization
checking as described in section 2.13 of this specification."
