Summary: why expat-1.95.6 can also NOT parse parameter entity ?

Initial Comment:
Both expat-1.2 and expat-1.95.6 can NOT parse 
parameter entity. Who can tell me what reason is it 
for ? 

Just like the follow sample can NOT pass expat parser:

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE aaa [
<!ENTITY % common "id  CDATA #REQUIRED">
<!ELEMENT aaa ANY>
<!ATTLIST aaa %common;>
]>
<aaa id="test"/>

"The external subset and external parameter entities also 
differ from the internal subset in that in them, parameter-
entity references are permitted within markup declarations, 
not only between markup declarations."

Receiving an error for your testcase is required, and 
therefore, it is not a bug.
