Comment (by mcs):

 Replying to [comment:4 mcs]:
 > 2. Modify NS_NewElement() to treat <math> and related tags as
 unknown/generic tags instead of MathML tags.  This seems like a good
 solution, but so far we have not been able to get it to work (other code
 still recognizes the elements as MathML).

 A quick update: we got the above approach to work.  The trick we are using
 is to replace the namespace on <math> and related elements with the
 generic XML namespace.  We will tie this to a pref. now.
