Actually, there is a MARC format for holdings data,

        http://www.loc.gov/marc/holdings/echdhome.html

And a number of the 8XX fields in the bib record can contain holdings
data:

        http://www.loc.gov/marc/bibliographic/ecbdhold.html

So it may not be totally unnatural to put your holdings-related facet
info into the MARC XML alongside the bib data. (Though you may want to
think about how to handle long serials runs.)

I would think that the big question is how (whether?) Voyager
exports holdings data.
