Question: I'd understood XSchema to be an attempt to eliminate the need to
do *any* DTD coding. If that's the case, why define general entities using
the DTD form? Wouldn't some thing like this work?:

<!DOCTYPE xschema SYSTEM xschema.dtd>
<xschema>
<Entities>
<EntityType id="greetings.content" repltext="#PCDATA"/>
</Entities>
<ElementType id="greetings">
<Content>
<Seq repeatable="no" optional="no">&greetings.content;</Seq>
</Content>
</ElementType>
</xschema>

That is, why not abstract entity declarations into XSchema form as well as
the element declarations?
