Title: Must a global domain channel be deployed before
it can be used?

Target: Assembly 1.2 WD 03

Description:

Via the "@target" and "@source" attributes defined
on a consumer & 
producer, the assembler can reference global domain channels.

In section 5.8, the presumed to be normative text reads "SCA runtimes
MUST support the use of domain channels [ASM????]."  That is
followed by:

"To create a Domain Channel, deploy a composite containing a channel
directly to the SCA Domain (i.e., do not use that composite as the 
implementation of some component in the Domain)."

Neither of the above indicate whether or not the global domain channel
can be used before it is referenced.

Proposal:

General theme: do not require the global domain channel to exist before
it can be used.

Specific text (needs refinement?):

In section 5.8, Paragraph #2, append:

When contributing artifacts to a domain that contain references to 
global domain channels that have not been created, the SCA runtime MUST
automatically create said global domain channels, and cannot reject such
contributions [ASM????].
