Notes
-----
There was no "origin" attribute to the "system" top-level container, though it is a configuration node.
As per the extension definition "The origin for any top-level configuration data nodes must be specified."

To choose an extension for top-level container in such cases, I would prefer one of the origin of its children and used "intended". , instead of "unknown".

This has already been discussed in the mail chain, but also mentioned here to help readers in future.
