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.
