Subject: i017 sp:RequiredElements mechanism
Description The spRequiredElements mechanism allows the policy to state whether a header element is required. This seems to provide an alternative to specifying required headers in WSDL/Schema. I had originally thoughth that this would be useful for other (non-header) elements. After thinking about it for a while I now think that WSDL/Schema validation should be used for that when needed. Proposal Drop the issue.
