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?
