> Yes they are, but so is also<title>. It can used either in the TEI-Header or in the TEI-Body. And it can be used to denote the title of a TEI-Document itself, the title of the source of the TEI-Document or the title of a bibliographic reference etc. But it is always the same element, since it's the context that matters in which it is applied. For instance<title> within<analytic> refers to a journal article while<title> in<monogr> refers to a book or journal title and title within<sourceDesc> is used to denote the title of a document external to the TEI-document.
Howewer a "title" is arguably a textual object of some kind (as witness
the fact that a title can also contain other titles), whereas "the
language of this document" is not. So I don't think the analogy is all
When textLang was introduced, I remember there was some discussion about
whether or not to use langUsage instead, and I think early versions of
the Master schema did exactly that.
If you have a transcription of a manuscript being described, then you
would record its language usage in the langUsage element. But if you do
not have a transcription -- just a msDesc -- then you would not.
You might also use langUsage to record the languages in which a
collection of manuscript descriptions were written. And those
descriptions might appear in the header, or the text of a document
(whereas, you will note, the definition of langUsage is that it relates
only to the languages used in the non-header part of a TEI document)
I think the workgroup felt that this was quite enough complication
without making the meaning of langUsage even further context dependent
as you seem to suggest.
