I have updated the stylesheet that extracts the schema from the document 
sources and updated the draft mathml3 area.

The schema changes are highlighted in red/yellow (css classes diff-del 
and diff-add) in:

http://www.w3.org/Math/draft-spec/appendixa-d.html

At the present time I haven't yet updated the schema distribution in 
Math/RelaxNG (I need to generate and test the dtd and XSD versions)
nor documented the changes in the changes appendix.

The changes so far appear to be

Units may be omitted from length attributes of mpadded

actiontype attribute is required on maction.
