Amaya 2.4,
released by the W3C late last year, provides support for XHTML. Direct
support for XML/CSS isn't there yet, but is planned, along with SVG support.
Amaya provides support for the proposed recommendation
of XHTML, and uses namespaces to permit the mixing of XHTML
with MathML. Cascading Style Sheets support now allows
more complex selectors based on ancestor elements and
attributes of those elements, and printing now works as
well.
Other
new features include changes to the user interface and
performance improvements. Source
