[GRAAP-WG] AgreementServiceReference

[Tianchao Li]

I'm not quite understanding the meaning of the 
wsag:AgreementServiceReferenceList resource property of Agreement port 
type and wsag:AgreementServiceReference. There is no further 
explanations in the specification, except for the following sentence:
"This OPTIONAL property specifies a list of named handles to the 
services of the agreement. The property MAY be empty and some services 
MAY be empty and some services MAY be omitted."
What exactly is the "services of the agreement"? And how is this 
resource property intended to be used?

Best regards,
