Loudmouth support for XEP extensions

[Ville]

Hi,

I'm evaluating XMPP libraries. Could you tell whether Loudmouth
supports
following XEP extensions? Our project is specifically interested of
following extensions:

XEP-0030 Service Discovery
XEP-0060 Publish-Subscribe
XEP-0070 Verifying HTTP Requests via XMPP
XEP-00174 Serverless Messaging

Could you send a list of supported XMPP extensions?

Thanks Ville Hyttinen
