NotUnderstood header in test 1205

Hi,
Someone here noticed:
        The first XPath in the response message for test 1205 checks for 
the NotUnderstood element in the SOAP header.  But according to the SOAP 
1.2 specs (section 5.4.8), implementations SHOULD provide a NotUnderstood 
header (i.e. they are not REQUIRED to do so).  So it seems like an 
implementation that does not provide this header shouldn't fail the test 
for this reason.

There has been a bunch of discussion about 1205 already so I'd like to 
discuss this to make sure we get it right. Anyone any thoughts?

Thanks,
David
