Re: [sca-assembly] Issue 26: SCA Composite Visibility: proposal

[David Booz <booz@us.ibm.com>]

Would you mind including the paragraph where you're attaching this text . line 1969 for me is in the middle of the schema snippet.

I think it might be this paragraph (?):

When a composite is used as a component implementation, it defines a boundary of visibility. Components within the composite cannot be referenced directly by the using component. The using component can only connect wires to the services and references of the used composite and set values for any properties of the composite. The internal construction of the composite is invisible to the using component.

In http://www.oasis-open.org/apps/org/workgroup/sca-assembly/download.php/28700/sca-assembly-1.1-spec-cd01-rev1.doc
Line  1969, add the following text to the end of the paragraph:
 
The boundary of visibility, sometimes called encapsulation, can be enforced when assembling components and composites, but such encapsulation structures might not be enforceable in  a particular implementation language. An implementation language may impose tighter restrictions on visibility, however any such restrictions  must not contradict the wiring and visibility requirements defined by this specification.
