Use of rft.identifier in COiNS?

Hi all,

I am trying to find the best way to include an item's accession number (i.e.
ILS system id) in a COiNS span.  This is in the context of library catalog
pages where I'd like to be able to retrieve the ILS accession number to
return to LibraryThing for Libraries.

I see no mention of an rft.identifier key/value pair on the COiNS site's
brief guide to books [1].  It does, however, appear as an element in the
COiNS online generator for generic items [2].

Googling returned a couple of results using rft.identifier to hold urls.

Can anyone enlighten me as to whether using rft.identifier to hold the ILS
accession number is valid?  Or suggest a more suitable key/value pair?

Thanks for any help you can provide.
