Re: [sca-assembly] [ASSEMBLY 180] Composite ref pseudo schema doesn't agreewith XML schema definitions - @autowire - PROPOSAL

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

Interesting. I went back and looked at the spec text again. In my proposal for ASSEMBLY-180 (in JIRA), I'm interpreting lines 1883 (cd03-rev2) in the spec to mean that autowire+promotion is possible, but unfortunately not defined. Mike, you seem to read those words as autowire was never intended to work in conjunction with promotion. I hadn't considered that interpretation. If we were to take that position, then effectively it says that autowire MUST be resolved within the bounds of a given composite (where the domain is a composite for domain level components) and that the failure to find targets within the composite results in an error?

Subject:	[sca-assembly] [NEW ISSUE] sca-core.xsd incorrectly has @autowire attribute for composite <reference/> element

---

Raiser:                        Mike Edwards 

Target:                        sca-assembly-1.1-spec-cd03-Rev2.pdf 

Description: 

The sca-core XSD declares the <composite/> <reference/> element to have an @autowire attribute: 

4190      <attribute name="autowire" type="boolean" use="optional"/> 

However, the specification section for the <composite/> <reference/> element does not contain a description of @autowire and the 
pseudo-schema does not contain the @autowire attribute. 

It was never intended that composite references should have an @autowire attribute.  If they did, this could lead to dangerous 
default autowire values occurring on components that used a composite containing a composite reference of this kind. 

Proposal: 

Remove the @autowire attibute from the <composite/> <reference/> element in the sca-core XSD. 

This means deleting line 4190 from CD03-Rev2. 


Yours,  Mike.
