21、n a technical imperative to extend the scope of the existing specification of the XFSManager to include new devices, such as the Card Embossing Unit.Similarly, there has also been pressure, through implementation experience and the advance of the Microsofttechnology, to extend the functionality and

22、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 isnow over 2 years old. Increasing market acceptance and the need to meet this demand is driving the Workshoptowards this r

23、elease.The clear direction of the CEN/ISSS XFS Workshop, therefore, is the delivery of a new Release 3.0specification based on a C API. It will be delivered with the promise of the protection of technical investment forexisting applications and the design to safeguard future developments.The CEN/ISS

24、S XFS Workshop gathers suppliers as well as banks and other financial service companies. A listof companies participating in this Workshop and in support of this CWA is available from the CEN/ISSSSecretariat.This CWA was formally approved by the XFS Workshop meeting on 2000-10-18. The specification

25、iscontinuously reviewed and commented in the CEN/ISSS Workshop on XFS. It is therefore expected that anupdate of the specification will be published in due time as a CWA, superseding this revision 3.0.The CWA is published as a multi-part document, consisting of:Part 1: Application Programming Interf

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 32 API. However, the XFS Workshop ha

39、s extended the franchise of multivendor software by encouraging the participation of both banks and vendors to take part in the deliberations ofthe creation of an industry standard. This move towards opening the participation beyond the BSVCs originalmembership has been very succesful with a current

40、 membership level of more than 20 companies.The fundamental aims of the XFS Workshop are to promote a clear and unambiguous specification for bothservice providers and application developers. This has been achieved to date by sub groups workingelectronically and quarterly meetings.The move from an X

41、FS 2.0 specification 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 pressure, t

42、hrough 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 isnow over 2 y

43、ears old. Increasing market acceptance and the need to meet this demand is driving the Workshoptowards this release.The clear direction of the XFS Workshop, therefore, is the delivery of a new Release 3.0 specification based ona C API.

44、ical investment for existing applicationsand the design to safeguard future developments.B55EB1B3E14C22109E918E8EA43EDB30F09CC9B7EF8DD9NormCD - Stand 2007-03 Page 8CWA 14050-1:20002. References1.
