[jira] Commented: (WSCOMMONS-267) OMSourcedElement SOAPHeaders will always be forceExpand()ed

["Rich Scheuerle (JIRA)" <ji...@apache.org>]

Rich Scheuerle commented on WSCOMMONS-267:
------------------------------------------

Design Proposal:

Add support for generic properties on the OMDataSource interface 
Add specific properties for MUST_UNDERSTAND and ROLE.
Change SOAPHeaderBlock to query that property first.  If the property is not set, then it gets the (attrribute) information the expansion.
This will allow an OMDataSource to communicate header specific information without requiring an expansion.

Side Effect:
Adding properties to OMDataSource would be a useful way to expose/add other capabilities.

I am going to start working on this issue.

> Working through trying to use WSCOMMONS-263 I've noticed that the OMSourcedElement SOAPHeader implementation doesn't take account of the special nature of SOAP Headers - namely that they have 'special' attributes e.g mustUnderstand and role that will get searched for regardless of the fact that the header is an OMSourcedElement. Calling getAttribute (which is how these attributes are retrieved under the covers) will cause a forceExpand which will negate the performance improvements intended.
