The RELAX NG abbreviated syntax.  There was also an abbreviated syntax used 
internally by some people in the WG for XML Schemas.

For design buffs, really what XML Namespaces did was move from
the course-grain namespaces of SGML to fine-grained namespaces.
SGML allowed an external entity to start with its own DOCTYPE
declarations (if the feature SUBDOC was supported). Goldfarb's
SGML Handbook even uses the term "name space" for subdocuments:
they have their own document type and their own ID scoping. 

For XML 2, if it keeps entities, it might be a good feature to
allow external entities to start with their own document type
declarations and have their own ID scoping.  So an entity
reference could do what xml:include attempts.
