[This is preliminary documentation and is subject to change.]
This property defaults to the latest version of the SIF Specification supported by the Adk.
Currently, it affects how SIF_Register messages are sent: if the ZIS supports SIF 1.1 or later, the Adk will send a SIF_Register with multiple SIF_Version elements, one for each version of the SIF Specification supported by the Adk. The first SIF_Version will be the version passed to the Adk.initialize method. If the ZIS does not support SIF 1.1 or later, the Adk will send a SIF_Register with a single SIF_Version element where the value is equal to the version passed to the Adk.initialize method.
