Setting DTD Validation Properties

You can validate XML request messages and response messages against associated document type definitions (DTD) by enabling DTD validation on the integration gateway.

When you set the ig.dtdLookup property equal to True (default), request and response messages are validated against any associated DTD.

References to DTDs may be inline pointers to files or references to URLs.

When you set the ig.dtdLookup property equal to False, no validation takes place—even if a DTD reference is supplied.

If the ig.dtdLookup property is removed or otherwise missing from the integrationGateway.properties file, the system responds as if the property is set to True, and request and response messages are validated against any associated DTD.
