[ISSUE 51] Composite Completeness - Updated proposal

[Mike Edwards <mike_edwards@uk.ibm.com>]

Folks,

Following on from the discussion at
the Assembly TC meeting earlier this week, here is an updated Proposal
to resolve Issue 51:

All line numbers here refer to sca-assembly-1.1-spec-cd01-rev2.doc

Replace lines 1948 - 1960 with the following
text

A composite used as a component implementation
must also honor a completeness contract. The services, references and properties
of the composite form a contract (represented by the component type of
the composite) which is relied upon by the using component.  The concept
of completeness of the composite implies:

1. For a composite used as a component
implementation, each composite service offered by the composite MUST promote
a component service of a component that is within the composite. 

2. For a composite used as a component
implementation, every component reference of components within the composite
with a multiplicity of 1..1 or 1..n MUST be wired or promoted (according
to the various rules for specifying target services for a component reference
described in section 5.3.1).

3. For a composite used as a component
implementation,  all properties of components within the composite,
where the underlying component implementation specifies "mustSupply=true"
for the property, MUST either specify a value for the property or source
the value from a composite property.
 
The component type of a composite is
defined by the set of composite service elements, composite reference elements
and composite property elements that are the children of the composite
element.
