See http://www.w3.org/TR/xml/#sec-references:
   "Well-formedness constraint: Entity Declared

In a document without any DTD, [...] for an entity reference that does 
not occur within the external subset or a parameter entity, the Name 
given in the entity reference MUST match that in an entity declaration 
that does not occur within the external subset or a parameter entity, 
except that well-formed documents need not declare any of the following 
entities: amp, lt, gt, apos, quot."

If you don't have a DTD, not even an internal subset, then you can only 
reference the predefined entities (amp, lt, gt, apos, quot). An entity 
reference to anything else violates well-formedness.

Not sure about that one.
