Nor am I, exactly. I can put system independent data in my system dependent
string, if I want. No harm, and much good results. The XML convention
should be that SDATA (or whatever other mechanism we choose) information
should be _preferably_ machine-processable, and _certainly_
human-meaningful. With an open set we can do little more. I agree that full
WSDs would be nice, but I can live without that a lot easier than I can
live with magic numbers.

If we go this route, it must not _require_ declarations in the DTD, though
a user might prefer to create entoties to reference common "glyph tags".
We need a built-in mechanism to solve this. We can reserve some syntactic
form to accomodate ISO-standard WSDs or whatever in the next revision.

A good point. We are going to have to specify (yechhhh!) how we (*shudder*)
will attach cascading style sheets (^blarg^) to our XML documents. We may
not ever get anything better in wide use.

But it does solve an important part of the problem.
