The normative binding schema specifies a global version attribute. This is used to identify the version of the binding declarations. For example, a future version of this specification may use the version attribute to specify backward compatibility. For this version of the specification, the version must always be 1.0. If any other version is specified, the configuration file will be skipped.

The version attribute must be specified in the root <bindings> element in the configuration file:

    <bindings version="1.0" ... />
