Same-document reference

Hi all,

just for clarification of what a same-document-Reference is: If I verify a 
ds:Signature which was in the Resource http://www.example.org/signature.xml 
and this ds:Signature contains this ds:Reference:

<Reference URI="http://www.example.org/signature.xml#resourceId" />

, this is _not_ a same-document reference, even if it points to the same 
signature file, correct?
