1.7.1 Versioning
This protocol uses the versioning mechanisms defined in the following specifications:
SOAP 1.1, as specified in [SOAP1.1].
SOAP 1.2, as specified in [SOAP1.2-1/2007] and [SOAP1.2-2/2007].
The data formatting and message processing of this protocol do not contain any further versioning mechanisms. The data itself is versioned to enable servers to determine whether clients need a full update or have an up-to-date version. This mechanism is described fully in sections 2 and 3 below.
