There are two types of MCE-based extensions: proprietary and standard.

As of now, there are no standardized MCE-based extensions.  But Japan 
has already proposed one such ("OOXML extension for Japanese Layout
Requirements" WG4 N0130).  Japan is expected to submit a new work item 
proposal for standardizinc MCE-based extensions of OOXML as an
separate multi-part standard.  The schemas proposed by Japan is
available at http://mailman.vse.cz/pipermail/sc34wg4/2010-February/001202.html

At present, all MS Office 2010 extensions are proprietary.  They are
described as part of MS Office 2010 specifications, but "Office 2010 Extensions Sampling" 
(WG4 N0133) should help.
