Description Greg Ritzinger 2005-01-20 20:17:25 UTC
Section 2.3.4, 2nd last paragraph, 1st sentence.   
   Question on constraint   
   "If two or more Channel Types SHOULD point to Role Types that MUST be
implemented by the same logical entity or organization, then the specified Role
Types MUST belong to the same Participant Type."   
   This restriction means that if channel type is present in an organization,
then only one participant type is allowed.   
   What is the reason for this restriction?   
   It would be reasonable to expect an organization to be more than one
Participant Type.

The restriction is valid because it makes no sense to have an organisation play 
two participants. This does not mean an organisation cannot have two 
participants 
in reality it just means that they are siloed. That is they are separate and 
not 
logically connected. So this delineates responsibilities within the logical 
participants in a CDL description. Therefore by definition it is correct and 
not 
further action is required to resolve this issue. 
There is no way, by definition, that a channel at one participant can point to 
the 
same thing in another. They cannot be the same channel because they are 
physically separate entities. 
Agreed that issue is therefore RESOLVED WON'T FIX.
