ok, the current development version has a <matrix> element, now. It is not 
quite finished from a user's perspective (cut / copy / paste are still 
missing, and there are a few cursor placement quirks), but from the 
perspective of a plugin developer, I consider it done.

See 
http://rkward.sourceforge.net/documents/devel/plugins/xmlelements.html#activeelements 
and 
http://rkward.sourceforge.net/documents/devel/plugins/elementproperties.html 
for documentation. There is also a testing plugin in the sources at 
rkward/plugins/testing/matrix1.xml, which should illustrate the main uses.

The dimensions can be manipulated by setting (or <connect>ing) the "rows" and 
"columns" properties.
