Évidemment!  It seems to me that if the tags are indended to be
purely specific to French, to help modern French speakers, then they 
should be in French - 16mes or whatever, rather than 16thc.

Whereas if they are indended to be part of a general system covering
all centuries and all languages then that system needs to be
worked out - 16thc or 1500s or whatever - along with recommendations
on use - as to the circumstances in which tags such as fr-1500s or 
frm-1600s are tolerated or even encouraged.
