I have to create some webservices based applications with compatibility for both the 1.0 and 1.1 versions. Though i did a analysis with the documents from the OASIS website i ws not able to infer much from them. Any help in this matter is welcome
Which standard are you referring to? There is no one "web services standard"; rather there are a whole bunch of standards related to one another: SOAP, WSDL, WS-Security, UDDI, WS Basic Profile, BPEL, ...
WS-Sec 1.1 is backwards compatible with 1.0, so supporting 1.1 should be sufficient. From the schema I see that there are new elements called "SignatureConfirmation" and "EncryptedHeader"; those must be for new functionality.
I checked the schema for 1.1 at http://docs.oasis-open.org/wss/v1.1/oasis-wss-wssecurity-secext-1.1.xsd and found that the namespace wsse has been changed to tns but i see a pretty small schema with the two elements mentioned EncryptedData and SignatureConfirmation. Can i get a complete 1.1 version schema some where the 1.0 version elements have been incuded ie the 1.1 is built over the 1.0 schema
