Behaviour¶

The <parameters> element in the service interface contains all the parameters sent as arguments to the <target> service.

Each of the parameters used by the specified target must be passed in a <parameter> child.

Format attribute¶

The format attribute specifies if the parameter passed to the target service has to be taken from the 'value' or 'grammar_entry' field of the request.
