Hello,

I am trying to extend the standard math collection with some symbols from
the Ralph Smith Formal font and some extra integral symbols from the txexa
font. I used the example from http://wiki.contextgarden.net/rsfs.

The problems I am having is
1) Some of the standard math symbols are overwritten as
shown by \showmathcharacters.
2) Alignment of left,right and middle is not working when I use matrices.

I really hope someone can help me.
Attached some test code.

Kind regards

Wim
