ah I'll see what I can do....

Although it really isn't so clear in a unicode setting that saying
U+03B1 is traditionally mapped as \alpha really helps.
U+03B1 is (as you know) textual Greek, and mapping it to \alpha
with the traditional definition of \alpha will just lead to tex errors.
Perhaps I can document that if the character element has mode="math" 
then the <latex> mapping is only assumed to work in math mode.

But in anycase the errors you reported initially were just errors
I think not relying on such details, I'll try to get that done.....
