The other SDD isn't in the XML spec. and informal testing suggests that it
is lost even to the search engines. Things move fast on the Web.

People seem to think that the word schema has some technical meaning that
I do not think it has. A schema is a document that describes the structure
of some other thing (in this case, another document).

Database schemata are a particular kind of schema. Electronics schemata
are another. We intend to develop yet another. I don't think that those
other kinds of schemata need to determine what our goals are.
As long as we are consistent in using the words "XSchema" I don't think
that there is any danger of confusion with the word "schema" as it is used
more widely (e.g. in the namespace specification), or with any other
particular schema language.
I think that "XSchema" is catchy, precise and otherwise a good name. It
may actually be more precise than "structure definition", because I'm not
