Re: [sca-assembly] [ISSUE 51] Composite Completeness - Updated proposal

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

Folks,

Someone pointed out that it would be
good to clarify that the composite used for an implementation is one post
<include/> processing.

So updating the proposal:

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 that, once all <include/> element processing
is performed on the composite: 

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.

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

3. For a composite used as a component implementation,  all properties
of components within the composite, where the underlying component implementation
