Subject: Re: [sca-policy] Wording for Issue 87


Hi,

I like the proposal. I have a question on the following statement from the draft:

With this design principle in mind, an XPath expression that is the value of an @appliesTo attribute designates what a policySet applies to. Note that the XPath expression will always be evaluated against the Domain Composite Infoset as described in Appendix Awithin the context of an attachment considering elements where binding instances or implementations are allowed to be present. The expression is evaluated against the parent element of any binding or implementation element. The policySet will apply to any child binding or implementation elements returned from the expression. So, for example, appliesTo=”//binding.ws” will match any web service binding. If appliesTo=”//binding.ws[@impl=’axis’]” then the policySet would apply only to web service bindings that have an @impl attribute with a value of ‘axis’.

Would the policySet apply to the ancestor elements of the selected binding/implementation elements?

Thanks,
Raymond
