As for its use elsewhere, what is the threshold that binds us to the
unsanctioned application of a tag? Is it 100 documents? 1000?
100,000? 0.1%? 1%?
I remain unconvinced that any extant application of META is sacrosanct,
but this is a side issue. I will be happy with ANY non-displaying tag.

how about CITATION? It has an obvious meaning and the additional
virtue of being the same in French.
In any case, let us not get bogged down in the tag... what is needed is
a non-displaying tag reserved specifically to the purpose of metadata.
