The closest you can come is by using the same trick XML Namespaces uses to
specify the namespace of an attribute: By adding another attribute.
External Unparsed Entities can be viewed as a named association between a
URI and a Notation. Since we all know that a URI can represent nearly
anything, you simply devise a representation of the "sibling attribute named
xxx" concept.
<!ENTITY bar-is-a-string SYSTEM "URI:LOCAL-ATTRIBUTE:bar" NDATA STRING>
<!ENTITY bar-is-a-int SYSTEM "URI:LOCAL-ATTRIBUTE:bar" NDATA INT>
<!ENTITY bar-is-a-float SYSTEM "URI:LOCAL-ATTRIBUTE:bar" NDATA FLOAT>
<!ATTLIST foo
bar CDATA #IMPLIED
local_types ENTITIES #IMPLIED
>
This, admittedly, is a declaration-heavy mechanism, and somewhat of a hack.
