I suppose this is an error on your part for "unparsed general entity"
or "parsed external entity".  Parsed general entities include
internal entities, references to which are permitted.

These are two distinct matters.

Clause 4.4 says that a *reference* to an external entity, parsed
or unparsed, is forbidden in attribute values.  Doing so is a violation
of the WFC "No External Entity References" in clause 3.1.

Clause 3.3.1 says that the value of an entity attribute must be
the name of (not a reference to) an unparsed external entity.
That is a validity constraint, since non-validating parsers may
not be aware of the type of an attribute, and are free to treat
them all as CDATA.
