To terminate a composition script evaluation normally during initial event processing, you can include a
<halt> element in a service input or output interceptor script block.
This stops the composition from including any more composition services. The SIS will also terminate any further evaluation of the interceptor upon encountering a
<halt> statement will only halt composition evaluation while the SIS is processing the initial event. If the SIS encounters a
<halt> while processing a subsequent event, or while evaluating an interceptor invoked directly by a SLEE application, the only effect will be to terminate further interceptor evaluation.
The syntax of a
<halt> statement for an interceptor is the same as that for compositions.
