One way to do this would be to use a semmantics element, with a link to
some external definition source, for example the OpenMath symbol H, from
the content dictionary setname2 (in the case of the quaternions). As in:
(if you're unfamiliar with the OpenMath concept, the site is:
http://www.openmath.org/ )
<semmantics>
<mi> H </mi>
<annotation-xml encoding="OpenMath">
<OMS cd="setname2" name="H"/>
</annotation-xml>
</semmantics>
another way would be to use the csymbol element with a definitionURL
attribute,
cheers,
Bill
