Representing Cancelations of Terms in Fractions

I'm working with education publishers on developing XML  
representations of things like textbooks and test prep manuals. These  
publishers are using primarily InDesign with InMath to author their  
equations. I can capture the raw InDesign data and InMath is working  
on an XML representation that captures the structure of the equations  
in a form that is almost MathML presentation.

But, one sticking point is the representation of equations with  
canceled terms, such as fractions where common terms are shown  
canceled with a diagonal strike out.

My understanding from reading the MathML 2 spec is that this can be  
represented using the menclose element with a notation of  
"updiagonalstrike" or "downdiagonalstrike". However, it's not  
rendered in Firefox and I can't MathType or Amaya to create anything  
other than a long division type enclosure.

My questions are:

1. is my understanding of menclose and *diagonalstrike correct in  
that this is the intended way to represent strikeouts in MathML?

2. Is there any MathML renderer that will render diagonal strikeouts  
today?

Thanks,

Eliot
