NAG has continued to pay an active role in XML Standardisation issues, David Carlisle acting as editor or co-editor for MathML For CSS profile, MathML 3.0 and a new document, http://www.w3.org/TR/xml-entity-names .
He also continues to play a role on the editorial team developing the OpenMath3 specification.

In addition to the XML work, David Carlisle took part in the
beta test of the STIX fonts which should in future make it much
easier to widely distribute mathematical documents without relying
on (for example TeX fonts, which are typically only available in
non standard encodings and formats). Comments were submitted to
the STIX group.
