No, it shouldn't. The relevant spec text is:

In a document without any DTD, a document with only an internal DTD 
subset which contains no parameter entity references, or a document with 
"standalone='yes'", 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. The declaration of a general entity MUST 
precede any reference to it which appears in a default value in an 
attribute-list declaration.


Your document doesn't have a DTD so it's malformed, no matter what 
parser reads it. :-(
