Properties and Parameter assignment

The assignment sections define the variable connection between the script execution and process model.

The following parameters are required.

**Ingoing Parameter**:

    - **MSG**: Input message

    - **path**: Denotes the schema in the schema document. If the parameter is missing or the value is `#`, it references the root schema. Typically, the value is a JSON path starting with `#`, as in the example above. It can also be the name of an anchor or a relative URL. Generally, it is a URI-Reference resolved against the current URI base. For details, see the specification of `$ref` in the corresponding JSON schema version.

    - **resultType**: A MIME type defining the type of the result, e.g., `application/xml` or `application/json` for a standard JSON schema result. If the value is missing, `application/json` is assumed.

**Outgoing parameter**:

    - **RESULTMSG**: Output message containing error records denoting warnings and errors that occurred while validating the message.
