The data are nonhierachical, but the tag categories arguables _are_.
This is why I suggested recoding it with slashes - it moves the supposed
hierachy out of the tag value, which remains nonhierachical as you remark,
and into the tag name, which is merely a string - the fact that it's
got a slash in it has no effect upon the parsing code (which adhering
to your own spec, allows all sorts of characters - including spaces,
which I though odd - in tag names).
So codewise it's no different to PERFORMER, and to the human the string
is very suggestive and descriptive.

Not if recast as above.
The problem with singular words (especially MEDIA and ADDENDUM) is that
they require the reader to have the whole spec in his/her head. By adding
a little more constructive categorisation to the tagname the user has
more context about the meaning.the reader to have the whole spec in

Just did. I agree that stuffing "VALUE=x" inside the tag _value_ is
asking for trouble - it's visually more noisy and certainly requires
parsing code to be written for what used to be flat scalars. So shift
it sideways into the tag name - no new parsing needed at all.

It's amazing how much 'mature wisdom' resembles being too tired.
