Good news,

The upgrade version (3.2.2.2228, not Pro) seems to handle correctly the equations pasted from MS equation editor and export to PDF the corresponding figures.
This is just very nice news and makes the upgrade worthy for me. Thanks Xara for having solved this painful issue for the editors of technical documents like me.

For the users of LaTeX, Xara seems quite able also to import LateX graphics created by the intelligent small IPE program (at least the PDF version of these graphics saved by IPE, I have not yet tested the EPS version).

This makes things simpler for us, LateX users.
