Service: Discovery

 
Supports the automated republication of any XNS specification in new and updated formats. The discovery service enables XNS to be expressed in terms of other technology specifications. For example, as soon as the current W3C WSDL Note is standardized by the W3C Web Services Working Group, XNSORG will be able to publish an updated enumeration of the WSDL service definition formats in the GetServiceDefinition message. As quickly as this updated service definition format is supported by at least one implementation, XNS developers will be able to get any XNS service definition in this new format.

See specifications: Web Services Description Language (WSDL) XML Schema Definition (XSD)
