Yes, which is why I suggested that the language tagged is limited to the
language of the resource.

We generally refer to this as "the language of the catalog." That isn't
coded in our metadata, AFAIK, although I wonder if CanMARC covered that,
since they often produce both an English-catalog and a French-catalog
version. Anyone?

Do browsers have markup within the page for this? I'm aware of the head
language encoding, but not of individual elements in the page. I guess
that CSS may add something - I'm not up with everything you can do
today. However, there is a big problem with trying to attribute
*language* to fields in bibliographic data. It only takes a few examples
to understand why:

1984 (book in German)
1984 (book in Hebrew)
1984 (book in English)

Marie Antoinette (book in English)
Marie Antoinette (book in Swedish)

Wong, Mario (a real name, altho not an author)

If special exceptions are need for the unified ideograms, then I see
that as an exception that affects display, not a general declaration of
the language of strings.
