	This minor change looks okay to me. I request the WG to assign
this one to the editors.

	Title


	Disambiguate notational convention for choice syntax 


	Description


	Framework and Attachment, section 2.1 each, state: 

	The character "|" is used to indicate a choice between
alternatives.
	 

	The character is used exactly twice. The first occurrence is in
the framework, section 4.2: 

	/wsp:Policy/(@wsu:Id | @xml:id)
	 

	The other occurrence is in attachment, section 3.4: 

	(05)   ( <wsp:Policy> </wsp:Policy> |
	 
	(06)     <wsp:PolicyReference> </wsp:PolicyReference> ) +
	 

	In both cases, the choice is exclusive. Note the + character
which allows multiple occurrences of Policy and PolicyReference in the
second case. Inclusive choice can always be solved as in the second
case. 


	Justification


	We should define the | syntax as exclusive right from the
beginning to ease reading and understanding. 


	Target


	Framework and Attachment 


	Proposal


	In Framework section 2.1 and Attachment section 2.1 replace
this: 

	The character "|" is used to indicate a choice between
alternatives.
	 

	with this: 

	The character "|" is used to indicate an exclusive choice
between alternatives.
