Please do.   We should try to make sure we cover the major standards, at least, and if there's an interpretation used by any widely-used office suite.

Marbux had a few pointers.  Here's what CSS says:
http://www.w3.org/TR/2006/PR-xsl11-20061006/#d0e5490
"The em-based relative units of measurement are defined in the Unicode
