Criteria 1:
Do you plan to ever provide your web service to environments that may not use webMethods IS to consume the service?
Criteria 2
Do you care whether your service implementation follows best practices recommended by the WS-I Basic Profile 1.0 or later?
If you answered “yes” to either of these two questions, then you should expose your service using document/literal style SOAP messaging.
A quick search in this forum, will turn up more details on the rationale behind this.
