Two points were brought to my attention by Monica Duke at UKOLN.

1)  Is there a way to specifically request -no- stylesheet?  An empty
    but present stylesheet parameter?

2)  In the SOAP document, in section 3, it reads:
       "A SOAP message MUST NOT contain Processing Instructions."
    As the XML declaration is not a processing instruction, this might
    include PIs -before- the Envelope.  At which point SRW must Never
    issue a stylesheet in the response, even if requested.  Does anyone
    know?
