13、CD - Stand 2007-03 Page 3CWA 14050-22:2000ForewordThis CWA is revision 3.0 of the XFS interface specification.The move from an XFS 2.0 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

14、 existing specification of the XFS Manager toinclude 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 capabilities of the existing devices covered by the

15、 specification.Finally, it is also clear that our customers and the market are asking for an update to a 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 CEN/ISSS XFS Wor

16、kshop, therefore, is the delivery of a new Release 3.0 specification basedon a C API. It will be delivered with the promise of the protection of technical investment for existing applications andthe design to safeguard future developments.The CEN/ISSS XFS Workshop gathers suppliers as well as banks

17、and other financial service companies. A list ofcompanies participating in this Workshop and in support of this CWA is available from 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/

18、ISSS Workshop on XFS. It is therefore expected that an update of thespecification 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 Interface (API) - Service Provider Interface (SPI); Pro

31、, Programmers ReferenceRevision 3.0, October 18, 20002.2 XFS form/media definition files in multi-vendor environmentsAlthough for most Service Providers directory location and extension of XFS form/media definition files areconfigurable through the registry, the capabilities of Service Providers and

32、 or actual hardware may vary. Therefore thefollowing considerations should be taken into account when applications use XFS form definition files with the purposeof running in a multi-vendor environment:- Physical display area dimensions may vary from one text terminal to another- Just-in-time form l

33、oading may not be supported by all Service Providers, which makes it impossible to createdynamic form files just before displaying them (which in return means that only the display data of the forms can bechanged, not the -layout data such as field positions)- Some form/media definition keywords may

34、 not be supported due to limitations of the hardware or software3.
