The spec also has the following statement:
4917 B.10 Domain
4918 An SCA Domain represents a set of Services providing an area of
Business functionality that is controlled
4919 by a single organization. As an example, for the accounts department in
a business, the SCA Domain
4920 might cover all finance-related functions, and it might contain a
series of composites dealing with specific
4921 areas of accounting, with one for Customer accounts, another dealing
with Accounts Payable.
4922 A Domain specifies the instantiation, configuration and connection of a
set of components, provided via
4923 one or more composite files. A Domain also contains Wires that connect
together the Components. A
4924 Domain does not contain promoted Services or promoted References, since
promotion has no meaning
4925 at the Domain level.
It's pretty clear that the promoted services/references at domain composite
level should be ignored. We can produce a warning
if it helps.
Thanks,
Raymond

Subject: Re: [2.x] Calculating Endpoints to promoted services
Well we should either process it OR point out through a warning that
it's being ignored. Silently ignoring it is what leads to confusion.
What is the proposal to process? That we should assume that they
configure the component references and services that they promote?
From the example given it would seem that this is a valid way to
configure a component service. However explicit words were put into
the spec to apparently discount this at the domain leve. I'd like to
get a sounding from one of the spec team on the implications of
definition of composite services and references at the domain level as
currently defined in the OASIS specs.
On a purely technical note (which is probably not that relevant yet)
we host service and reference endpoints and endpoint references on
components. Composite services and references form part of the
component type of a component that uses the composite through
implementation.composite and hence that's where the endpoint and
endpoint references are dealt with.
