Hi Paul,

thank you. That is a good starting point.

Is there someone, who actually implemented a filter for MathML?
Maybe someone provides a CMS, where users can publish MathML code that
is displayed after being filtered?
While I understand that this would not be a formal specification or a
gurantee that the filtered MathML is secure, but it would give some
evidence that this subset is ok, with todays browsers.
