Re: [sca-assembly] ISSUE 254: Names of channels should allow "/", should bedeclared as URIs....
Apologies Anish, I was using a version from last year - the section in question had been explicitly added so I assumed it was still current.. However I was puzzled about how it related to the "remove multiple bindings" issue. I will use the new wd03 from now on.

I thought we got rid of this, now that we have restricted channels to a single binding. -Anish -- > > Regards > > Peter Niblett > IBM Senior Technical Staff Member > Member of the IBM Academy of Technology > +44 1962 815055 > +44 7825 657662 (mobile) > > > > > From: Martin Chapman <> > To: OASIS SCA Assembly <> > Date: 01/02/2011 13:48 > Subject: [sca-assembly] ISSUE 254: Names of channels should allow "/", > should be declared as URIs.... > ------------------------------------------------------------------------ > > > > The only concern I have about this issue/proposal is that its seems to > imply that there is a relationship between global channels that is > somehow understood by the SCA Runtime.
