Correct.

The wrapper message could be localized, and if all you want is to add
a URI then no localization would be required.

Finally, this would be for site-local uses.  At many sites
localization is not required.

As well as http/https URIs pointing to servers within the intranet.
This would be fully under the control of the config file author.
