A _Capture_ element can get ANY attributes (as well as ANY content)
pass all Box properties to the insertMathToken method as attributes (not just a seperate set of attributes)
->setAttribute only sets attributes that are allowed by the model (or are namespaced)
textification of array cells in some circumstances
pass all properties to the Box for DefMath that produce primitves
always set displaystyle on mtable, since mozilla sometimes forgets
a CD should have meaning=commutative-diagram
better \middle that avoids the XMWrap
fixup mathstyle adjustment for \over,etal to get correct styles; simplify \big etal to avoid XMWrap; provide generalized alignment binding machinery for matrix and cases objects, and a better logical model for the content form (using XMDual)
use the general alignment binding tools from TeX for matrix and cases, to provide generalized matrix and cases environments with proper logical structure
rewrite \Biglb etc similarly to \big in TeX
update tests for new logical structure of matrices and cases
