In a publish-and-subscribe solution, Integration Server validates a published document against the associated publishable document type. Validation occurs immediately after the publishing service executes. If Integration Server determines that the published document is invalid (that is, the published document does not conform to the associated publishable document type), the publishing service returns a service exception that indicates the validation error. Integration Server does not publish the document.

While document validation ensures that document subscribers receive valid documents only, it can be an expensive operation in terms of resources and performance. In some situations, you might not want to validate the published document. For example, you might want to disable document validation when publishing documents that were already validated. Suppose that a back-end resource, created and validated the document and then sent it to Integration Server. If Integration Server in turn, publishes the document to Broker, you might not need to validate the document when publishing it because it was already validated by the back-end resource. You might also want to disable all document validation when publishing native Broker events.

Integration Server provides two settings that you can use to configure validation for published documents.
