* ensure that the {@code Document} argument is empty aside from
* being pre-configured to be in the proper namespace for an
* Application Configuration Resources file: {@code
* http://xmlns.jcp.org/xml/ns/javaee}. Implementations of this
* service must ensure that any changes made to the argument {@code
* Document} conform to that schema as defined in the specification.
* The JSF runtime is not required to validate the {@code Document}
* after control returns from the service implementation, though it
* may do so.
*
*
*
* Ordering of Artifacts
*
* If the document is made to contain an {@code } element,
* as specified in the section Ordering of Artifacts in the
* specification prose document, the document will be prioritized
* accordingly. Otherwise, the runtime must place the document in the
* list of other Application Configuration Resources documents at the
* "lowest" priority, meaning any conflicts that may arise between the
* argument document and any other Application Configuration Resources
* are resolved in favor of the other document.
