Re: [sca-bindings-comment] Comments on binding specs

[Simon Holdsworth <simon_holdsworth@uk.ibm.com>]

Thank you for your interest in the SCA Bindings specifications.
The TC welcomes your comments and has discussed them; as a result of your
comments we have one new issue. Please refer to each comment for the TC's
response. 

sca-jmsbinding-1.1 spec

• In the JMS Binding Schema there is no <request> element
  
  The <request> element is implicitly <binding.jms> element.  For one-way scenarios, which are likely to be common with JMS applications, always having this extra element present in the binding seems an unnecessary overhead.  We do not propose to make any changes to the specification.
  
• On line 198, what happens if @create and @jndiName have values. Which takes precedence?
  
  The lines following 198 explain the relationship between the @create attribute and the @jndiName attribute.  All cases are covered, given that the @create attribute has a default value of "ifNotExist".  Each value of @create defines whether or not @jndiName must have a value or not, and if a value is required, the conditions that value must satisfy. We do not propose to make any changes to the specification.
  
• On line 364, for default operation selection, is it possible for an operation to be undetermined? If so, is an error thrown?
  
  The algorithm as described always has a selected operation name determined, which defaults to "onMessage" if none of the other conditions are met.  However the text in section 4 that describes the resolved operation name does not currently cover the case where the resolved operation name is not one of the operations in the target components interface, so this needs to be clarified by an update to the document.  The TC has resolved to add a normative statement to indicate that an error must be raised in this case.

sca-wsbinding-1.1 spec

• Should a default operation selection algorithm be detailed here? Or is it assumed from other referenced specifications?
  
  The relevant web service specifications have a way to figure out the operation. For example the WS-Addressing wsa:Action SOAP header block so no operation selection algorithm is required.  We do not propose to make any changes to the specification.
