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. 13621 1 chrisfer 2007-01-16 21:58:25 +0000 RESOLUTION: 4177 resolved by adding exclusive as proposed in http://lists.w3.org/Archives/Public/public-ws-policy/2007Jan/0056.html See http://www.w3.org/2007/01/16-ws-policy-irc#T21-57-25
