Subject: [provision] Extended Request - modified
Extended Request/Response Updated Proposal Hi all, Following the last conference call and a closer review of the proposal for the Extended Request/Response, I am still concerned that the issue of the provider ID is unfortunately unsolved. As you may recall, my concern was that the original extended request draft did not mandate an appropriate identification of the provider responsible for the specific extended request/response dialect, stressing a possible need for a ‘ProvID-like’ attribute. Although not necessarily critical for all situations, such identification may indeed be crucial for various scenarios and not solely for the purpose of request identification. The last extended request/response draft introduced the ProviderDefined identifier for this purpose, but being still an optional choice, its practical value is reduced considerably. Based on the above I wish to submit for consideration a modified proposal presenting three alternative ways to support proper provider identification; closely modeled on the last draft, the alternatives portray various routes to achieve proper identification sans deviating from the already accepted framework. Though all alternatives are serviceable, they are presented here in descending preference order - starting from Alternative 1 (preferred alternative). Alternatives Alternative 1: one operationID type: ProviderOperationIdentifier This alternative specifies the use of the ProviderOperationIdentifier as the sole type for operationIdentifier.
