xhtml-relaxng - 20220510-3 main

This package contains an implementation in RELAX NG of the modularization of
XHTML specified by the Modularization of XHTML Recommendation
.
The RELAX NG schema has not been mechanically derived from the DTDs. Rather,
it has been hand-crafted so as to produce a good quality RELAX NG schema.
However, it may well contain bugs.
