Sections 5,6,7 : The service definitions in 5,6,7 use "invoked by" and "service provider". Please define these terms as used here.

I am not an expert in SOA so help me understand.

[SOA-RM] line 192 states the following:
In general, entities (people and organizations) offer capabilities and act as service providers. Those with needs who make use of services are referred to as service consumers. The service description allows prospective consumers to decide if the service is suitable for their current needs and establishes whether a consumer satisfies any requirements of the service provider. (Note, service providers and service consumers are sometimes referred to jointly as service participants.)

For the tables in Sections 5,6 7 the use the terms "invoked by" and "service provider". Would it be better to use the term "service consumer" instead of "invoked by"?

[SOA-RM] line 482 of the same reference states:

The action model of a service is the characterization of the actions that may be invoked against the service.

So it seems that some services result in actions invoked by the service provider but not directly by the service consumer.
