I've added support for XEP-0128 in general. Now it is possible to add following entry to the etc/config.tdsl:

'disco-extensions' = {
    'abuse-addresses' = [ 'mailto:support@tigase.net', 'xmpp:admins@tigase.net' ]
}

adds abuse-addresses field with 2 values (as above).

Could you add this to documentation as well?

It works

However it got me thinking. Supposedly we are moving towards "repository-based" configuration, so it would make sense to allow configuring it ad-hoc without the need to restart the instance(s) -- what do you think?

Yes, I thought about applying it to tigase.im instances but instead of simple configuration change this would require going through the whole cycle of creating image…

We should finish the task with the reconfiguration of the server at runtime. Then moving config file to the shared folder would allow us to easy reconfigure server using ad-hoc commands.

IMHO we should avoid re-writing configuration file. It was understandable during conversion to TDSL, but changing configuration by re-writing it feels like a bad idea.

After talk with Andrzej we settled on: those configuration options should be part of VHostItem and DefaultVHostItem, created #8791 to track it.
