> So is it ok to lang tag mbox without affecting mbox_sha1sum? More specifically, does an mbox literal with lang tags hash to the same mbox_sha1sum as the same literal without the lang tags (or ignoring lang tags?

foaf:mbox as an RDF property, doesn't take literal values, just points
to a resource (bnode or URI reference), and xml:lang doesn't affect
those. When hashing the (typically mailto:) mailbox URI to 
generate mbox_sha1sum, we strip out surrounding whitespace and ignore 
language tagging, which is why lang-tagging the resulting textual
property should be meaningless.

Probably the 'right' thing to do would to have been to use RDF 
datatyping, however I find the instance data syntax unhappily verbose,
so instead we have to work around the lang tag issues.

hope this makes sense,
