It seems so. Then let's just change it like that:
<!ENTITY % CLOSE ">">
<!ENTITY % ELEMNAME "doc">
<!ENTITY % ATTNAME "att">
<!ATTLIST%ELEMNAME;%ATTNAME; CDATA #FIXED "value"%CLOSE;
That should be well-formed, I think.

Yes, because it is in a position of a DeclSep .

Not necessarily. See the changed example above.

Well, almost, IMO - see above.
