I think that's what I proposed in response to Drew's original message, and what 
Stefan suggests (it's a natural extension of overlay categories).  But I'm not 
sure it's what Drew had in mind.

Specifically, Drew (IIUC) would like *faces* to behave as these hypothetical 
'defprop's.  This way, all the existing machinery on faces could be reused.
