Re: [sca-assembly] ISSUE 37: Need to clarify contents of an SCA Domain virtual composite

[Scott Vorthmann <scottv@tibco.com>]

As promised, my proposal for resolving issue 37.

Section headings and line numbers refer to cd02-rev1 (attached to a  
recent email from Mike).

2.1,  156:

remove composites X and Z from the picture, replace with a new
composite X with component C wiring to A in Y

6,  1207:

change "elements" to "components and wires"

12.6,  3981-2:

Like other composites, it contains components and wires.  Unlike other  
composites,
there are no promoted services or references, since there is no  
defined scope for visibility
larger than the domain.

12.6.1,  4006-8:

All of the composite’s components become top-level components.
The meaning of any promoted services and references in the supplied  
composite is not defined;
since there is no composite scope outside the domain composite, the  
usual idea of promotion has
no utility.

B.10,  5023:

replace: "The domain, like a composite, also has Services and  
References.
Domains also contain Wires which connect together the Components,  
Services and References."

with:  "A Domain also contains Wires that connect together the  
Components.  A Domain does
not contain Services or References, since promotion has no meaning at  
the Domain level."
