I am actually not so interpreting SDATA entities, which is why I pointed
to TEI WSDs and Harry Gaylord's article in my message.

I care not one whit about SDATA, as I have said.

What I do care about is retaining the ability to give a
human-readable description of a character or glyph in such
a way that an application can be expected to present it to the user,
rather like the ALT attribute to an image in HTML.

SDATA entities give you a way of doing that today -- if you like,
you can do
    <!Entity x SDATA "the latin letter small x">
The ISO 10646 user space alone does not do that.

James' suggestion of the form
<!Entity Klingon.W '<char alt="Klongon letter W">W</char>'>
is a good one and I could live with it, but would like it explicitly
mentioned somewhere in the Famous Twenty Pages.

James mentioned the use of DSSSL, but I have not been assuming that
every XML implementation would be required to support DSSSL.
If they are, I'm out of here right now.

Again, I'm not arguing for keeping SDATA, but only for having a
mnemonic string.  The WSD would be a good way to do it, but I
can live with James' hack if necessary.  I gree with you that
SDATA doesn't handle all of te problem either.
