I'm afraid that I must ask what these are to be used for. I used to think
that this was a problem, and now I don't see how we really need these
declarations. They only seem to be relevant for typesetting, and if
typesetting is the task, then you'll only get correct results witha
well-known DTD or stylesheet in any case -- so why have the declarations.
I'm not concerned about readers taking correct stylesheets and later
mucking them up -- that will always be possible.

My problem is that I'm no longer able to see why this information has to go
with the document... I can't think of a case where it's necessary, and tons
of other information about the meanings of tags, etc, is not also necessary.
Also, since XML passes all whitespace, the only case we can deal with is
one where its essential to _ignore_ whitespace in the source document.
