Re: [sca-policy] Can we use appliesTo="sca:binding" or appliesTo="sca:implementation"to select all bindings or implementations?

Hi Raymond:
In XPath 1.0 the expression "sca:binding.ws" will select all nodes 
called sca:binding that are children of the
context node.

Look in the section 2.5 of the spec.  The first bullet says:

    * |para| selects the |para| element children of the context node

All the best, Ashok
