The stylesheets displaying (all) Content Dictionaries at OpenMath.org
have been updated at the same time  All OpenMath examples are now shown

grammar supported by existing software. It has been developed as part of
the SCIEnce project and presented at OM2009 (although I am to blame for
the particular XSLT conversion to pocorn used in the CD stylesheets, so
please report any bugs to me)
