The Canonical Model is too large for effective use in message development. Instead, a subset schema that only contains what is required by the message while maintaining alignment to the model is required. igniteXML has removed the manual process of creating subset schemas using an easy to use web interface that allows anyone to search and navigate the model (directly or through the application vocabulary familiar to them), find the components within the model that meet their message requirements, add the components to a pick list, and auto-generate a run-time optimized XML Schema. Valid message payloads are developed at a fraction of the time.
