issue 243: is default channel configurable? Proposals

[Anish Karmarkar <Anish.Karmarkar@oracle.com>]

I took an AI to provide two competing proposals for resolving issue 243.

Proposal 1: allow the default channel to be configurable.

In section 5.9 of WD06, add the following --
The default domain channel, like any domain channel, can be configured. 
Configuring the default domain channel requires one to deploy a domain 
composite containing a channel with the 'name' attribute value set to 
"/". Note that since the default domain channel always exists, 
configuring the default domain channel in a running system is equivalent 
to reconfiguring an existing channel and will be subject to restrictions 
and conditions imposed by a runtime on reconfiguration of domain channels.


Proposal 2: do not allow the default channel to be configured.

In section 5.9 of WD06, add the following --
Since the default channel always exists, one is not allowed to deploy 
and configure the default channel using a domain composite. This does 
not prohibit runtimes from defining implementation-specific ways of 
statically or dynamically specifying configuration of the default channel.
