Yes, but there isn't anything important about the whitespace within tags:

I agree with the rest of your comments.
Even whitespace within tags has its uses, e.g., to break up very long
lines where adding whitespace outside tags would change the, uh, infoset.
I personally think the distinction comes down to hand-authored XML vs.
program-generated XML. The latter would mostly be satisifed with
exchanging infosets. The former, mostly not.
Here are the things human authors _need_ that aren't in the Infoset:
1) A way to include other documents.
2) A way to specify characters that aren't directly supported by the
3) Comments. Documents are read by other humans, too.
4) Validation. (There's no way one could ever produce a DocBook document
if there weren't some automatic way to check it.)
I'm kind of amused by Allesandro's harping on the need for a choice of
attribute value delimiters. Ok, you're about to write a value that
contains the " character. There are two ways to do it: Delimit the value
with ' characters (that choice we don't need) or escape the value with
" (those entities we don't need).
Not a problem for programs, but there are still a few of us humans out
there, scribbling away.
