Re: "interface" attribute info item on service component

Hi Arthur,

Thanks for the detailed explanation.
Maybe I was not clear in my question (1) .
I was explicitly referring to the "interface" attribute on the <service>
nodes. Woudnt the interfaces that are referred to as attributes on the
<service> nodes need to have atleast one operation within them, either
declared / inherited ? Would it make sense to explicitly state this in the
spec ?
Similarly, for the second question, I was referring to those bindings that
are referred to from within the <endpoint> node as an attribute - wdnt these
referred bindings need to be referring to an interface mandatorily ? Again,
if it makes sense, would it better if we explicitly state ithis in the spec
?

I would also appreciate your thoughts on point (3).

Thanks again!

rgds,
Ram
