Long Tags Codes etc. again

Folks
It has been said

1. Human readability by domain experts as well as software specialist,
is a requirement for XML documents.

Yes true, but if we were to adopt a 'code' as a tag then it would still be
human readable i.e it is ASCII but the meaning would be obscured to the
casual/uneducated reader. It is not beyond the wit of comptuing to look up
the 'code' and make it friendly to the casual reader. Also, given the
human reader could have some language other than English as his/her mother
tongue, then the look up could be keyed on Language Code + tag code. Is this
even better than having a long English tag?

Even with 'long' tag names, which allow readability in English, there
still remains a problem, in that the tag does not convey the complete
meaning - otherwise we would not need any semantics at all.

Again we must ask a similar question to the one which I posed before.

How much of the semantics should be in the tag and how much in the
actual semantic description of the element.

There is a temptation to write an 'essay' in the tag.

Anybody got thoughts on this one ?
