Remarks

The SOAP versions currently available are SOAP 1.1 and SOAP 1.2. There is an EnvelopeVersion for each of these versions of SOAP that can be recovered using the Soap11 and Soap12 properties. There is also a None message version that is used to sent and receive XML messages that do not use SOAP formatting. The processing roles associated with each message version can be recovered using the NextDestinationActorValue property and the GetUltimateDestinationActorValues method.

Properties

NextDestinationActorValue	Gets a string that contains the URI name for the SOAP role associated with the current message version for the next destination.
None	Gets the envelope version not using a version of SOAP.
Soap11	Gets the SOAP1.1 envelope version.
Soap12	Gets the SOAP1.2 envelope version.

Methods

GetUltimateDestinationActorValues()	Gets a string that contains the URI name for the SOAP role associated with the current message version for the ultimate destination.
ToString()	Gets a string that represents the current envelope version.
