hi, i'm currently learning the XML 1.1 Specification,
04 February 2004.
I have a problem understanding the statement of 
WFC Entity Declared.
A quote from this WFC :
"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."
Does "parameter entity" in phrase :
" ... for an entity reference that does not occur within the   external subset or a parameter entity ..." and in phrase :
" ... entity declaration that does not occur within the external          subset or a parameter entity." 
refers to both internal and external parameter entity ?

If it is true, then is it right that violation of this WFC 
occurs when standalone="yes" and :   
   - there exists an entity-reference in document-content 
     or in internal subset, and
   - that entity is declared in external subset or 
     in parameter entity (internal / external) ?
I just want to make sure that my understanding of that WFC is 
correct.
many thanks,
