13、0 specification (CWA 13449) to a 3.0 specification has been prompted by a series of factors.Initially, there has been a technical imperative to extend the scope of the existing specification of the XFS Manager toinclude new devices, such as the Card Embossing Unit.Similarly, there has also been pres

14、sure, through implementation experience and the advance of the Microsofttechnology, to extend the functionality and capabilities of the existing devices covered by the specification.Finally, it is also clear that our customers and the market are asking for an update to a specification, which is now

15、over 2years old. Increasing market acceptance and the need to meet this demand is driving the Workshop towards this release.The clear direction of the CEN/ISSS XFS Workshop, therefore, is the delivery of a new Release 3.0 specification basedon a C API. It will be delivered with the promise of the pr

16、otection of technical investment for existing applications andthe design to safeguard future developments.The CEN/ISSS XFS Workshop gathers suppliers as well as banks and other financial service companies. A list ofcompanies participating in this Workshop and in support of this CWA is available from

17、 the CEN/ISSS Secretariat.This CWA was formally approved by the XFS Workshop meeting on 2000-10-18. The specification is continuouslyreviewed and commented in the CEN/ISSS Workshop on XFS. It is therefore expected that an update of thespecification will be published in due time as a CWA, superseding

Introduction1.1 Background to Release 3.0The CEN XFS Workshop is a continuation of the Banking Solution Vendors Council workshop and maintains atechnical commitment to the Win 3

32、2 API. However, the XFS Workshop has extended the franchise of multi vendorsoftware by encouraging the participation of both banks and vendors to take part in the deliberations of the creation ofan industry standard. This move towards opening the participation beyond the BSVCs original membership ha

33、s beenvery succesful with a current membership level of more than 20 companies.The fundamental aims of the XFS Workshop are to promote a clear and unambiguous specification for both serviceproviders and application developers. This has been achieved to date by sub groups working electronically and q

34、uarterlymeetings.The move from an XFS 2.0 specification to a 3.0 specification has been prompted by a series of factors. Initially, therehas been a technical imperative to extend the scope of the existing specification of the XFS Manager to include newdevices, such as the Card Embossing Unit.Similar

35、ly, there has also been pressure, through implementation experience and the advance of the Microsofttechnology, to extend the functionality and capabilities of the existing devices covered by the specification.Finally, it is also clear that our customers and the market are asking for an update to a

36、specification, which is now over 2years old. Increasing market acceptance and the need to meet this demand is driving the Workshop towards this release.The clear direction of the XFS Workshop, therefore, is the delivery of a new Release 3.0 specification based on a C API.It will be delivered with th

37、e promise of the protection of technical investment for existing applications and the design tosafeguard future developments.1.2 XFS Service-Specific ProgrammingThe service classes are defined by their service-specific commands and the associated data structures, error codes,messages, etc. These com

38、mands are used to request functions that are specific to one or more classes of serviceproviders, but not all of them, and therefore are not included in the common API for basic or administration functions.When a service-specific command is common among two or more classes of service providers, the

39、syntax of thecommand is as similar as possible across all services, since a major objective of the Extensions for Financial Services isto standardize command codes and structures for the broadest variety of services. For example, using the WFSExecutefunction, the commands to read data from various s

40、ervices are as similar as possible to each other in their syntax anddata structures.In general, the specific command set for a service class is defined as the union of the sets of specific capabilities likely tobe provided by the developers of the services of that class; thus any particular device w

41、ill normally support only a subsetof the command set defined for the class.There are three cases in which a service provider may receive a service-specific command that it does not support:The requested capability is defined for the class of service providers by the XFS specification, the particular

42、 vendorimplementation of that service does not support it, and the unsupported capability is not considered to befundamental to the service. In this case, the service provider returns a successful completion, but does no operation.An example would be a request from an application to turn on a contro

43、l indicator on a passbook printer; the serviceprovider recognizes the command, but since the passbook printer it is managing does not include that indicator, theservice provider does no operation and returns a successful completion to the application.B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9Nor

In this ca

45、se, a WFS_ERR_UNSUPP_COMMAND error is returned to the calling application. Anexample would be a request from an application to a cash dispenser to dispense coins; the service providerrecognizes the command but, since the cash dispenser it is managing dispenses only notes, returns this error.The requested capability is not defined for the class of service providers by the XFS specification. In this case, aWFS_ERR_INVALID_COMMAND error is returned to the calling
