Do you know about the 'altimg' attribute on the <math> element?  If
not, you may want to take a look, since it is for the situation you
describe. 

However, to answer your specific question, at least for MathPlayer, by
default it will ignore unknown attributes on the <math> element.  (It
has stricter validation modes that will catch this, but the average
end-user can't turn these modes on.)
