Description:

The description of the Composite Reference
@multiplicity attribute between lines 1447-1460 conflicts
with both the pseudo-schema and the
XSD for SCA Assembly.

The current text implies that the attribute
is required (ie (1..1) ).  The text does not describe a default
value when one is declared in the XSD.

Proposal:

Modify the text between 1447-1460 to
read as follows:

        multiplicity
:  0..1|1..1|0..n|1..n  (0..1)  - Defines the number
of wires that can connect the reference to target services.  The multiplicity
can have the following values

o        0..1 – zero or one wire can have the reference as a source

o        1..1 – one wire can have the reference as a source

o        0..n - zero or more wires can have the reference as a source

o        1..n – one or more wires can have the reference as a source

The default value for the @multiplicity attribute is 1..1.

The value specified for the multiplicity attribute of a composite reference MUST be compatible with the multiplicity specified on each of the promoted component references, i.e. the multiplicity has to be equal or further restrict. So multiplicity 0..1 can be used where the promoted component reference has multiplicity 0..n, multiplicity 1..1 can be used where the promoted component reference has multiplicity 0..n or 1..n and multiplicity 1..n can be used where the promoted component reference has multiplicity 0..n., However, a composite reference of multiplicity 0..n or 1..n cannot be used to promote a component reference of multiplicity 0..1 or 1..1 respectively.
