Status and scope of openmath branch

[kpeeters]

I am working on using MicroTeX for the notebook interface of my symbolic computer algebra software Cadabra. This all works very nicely, many thanks for the great work!

In order to know where to focus my attention, can someone perhaps give a quick summary of the status of the openmath branch, and the scope of features it tries to include beyond the main branch? Am I best off using openmath or is it, for stability, better to stick to the main branch for now?
