You might want to validate an individual document (IData object) in the pipeline instead of the entire pipeline. Use the pub.schema:validate service to validate a single document (IData object) in the pipeline against an IS document type.

For example, suppose that you invoke the pub.client.ldap:search service in a flow to retrieve an IData object from an LDAP directory service. If you want to validate that object before you use it in other services, invoke the pub.schema:validate service after retrieving the object. As another example, you might want to validate an XML document that has been converted to a document (IData object). You would use the pub.schema:validate service to validate the resulting document (IData object) against an IS document type.

The pub.schema:validate service considers a document (IData object) to be valid when it complies with the structural and content constraints described in the IS document type it is validated against. This service returns a string that indicates whether validation was successful and an IData array that contains any validation errors. When you insert the pub.schema:validate service into a flow service, you can specify the maximum number of errors that the service can collect. You can also specify whether the pub.schema:validate service should fail if the document (IData object) is invalid.
