The entity files distributed in the zip file linked from the MathML 1.01
REC were generated from this file using dsssl, and just include the
entity sets used in MathML. Some of the ISO entity sets not needed for
MathML are not distributed, although the source information is in
unicode.xml.

The xsl below will extract an XML compatible entity file (or files) from
unicode.xml, just edit it to get the sets you want, as posted it just
makes one for ISOPUB from ISO 8879. It uses the xt:document extension
for xt. Information for how to make it work with other XSL engines
greatfully received. (Vendor neutral extension namespace, perhaps?:-)
