  Well, actually for XPath processing entities are substitued and
there will be a single text node child as when using xmllint --noent

paphio:~/XML -> xmllint --noent --debug tst2.xml 
DOCUMENT
version=1.0
URL=tst2.xml
standalone=true
  DTD(doc)
    ENTITYDECL(test), internal
     content=a sample as well as 
      TEXT
        content=a sample as well as 
PBM: Node has no next and not last of list
  ELEMENT doc
    TEXT
      content=This is a sample as well as  a test
paphio:~/XML -> 

  xsltproc switch on entity substitution automatically,
