3. Validating CDA The previous slide shows a schematic of the CDA checker. You provide an on-the-wire xml example The tool checks the example against the on-the-wire CDA schema, and on-the-wire schematrons The tool converts the on-the-wire example to a templated equivalent The tool checks the templated example against the templated CDA schema, and templated schematron The results of both the on-the-wire and templated checks are shown in a browser Alternatively, the tool can be used to render an example
