ResponseCriteria identifies the content that is returned, given a Get query
success or the response from the Process. In essence, the expression here
has the effect of filtering the part(s) of the found element(s) that are to
ReturnCriteria plays no role in the query itself or the process. That is
handled as a match against the request BOD's noun exemplar.
ReturnCriteria allows the sender of the BOD to indicate which information
(down to the field level) is requested to be returned, given that the query
has been successful in matching the exemplar to existing nouns.
That is, in a GetListPurchaseOrder, if one or more PurchaseOrders with a
TotalPrice = $1M were found, ReturnCriteria tells the BOD recipient which
parts of the PurchaseOrder should be populated with content when the
response (ShowPurchaseOrder) is formulated.
The expressionLanguage indicates the expression language being used. In
order for the ReturnCriteria expression to be evaluable by the BOD
recipient, the recipient must be capable of processing and interpreting the
specified expression language. XPath is the default, due to its ubiquity
among XML processing technologies.
