A lot of XEP versions are missing in .doap file

Dear @processone team,

A lot of XEP versions are missing in .doap file, recent too :/

It is important and it permits to easy update the support.

Some examples:

• XEP-0013 to update (like other in the same case): https://github.com/processone/xmpp/blob/master/xmpp.doap#L58
• XEP-0016 to update (like other in the same case): https://github.com/processone/xmpp/blob/master/xmpp.doap#L67
• XEP-0033: https://github.com/processone/xmpp/blob/master/xmpp.doap#L103
• XEP-0047: https://github.com/processone/xmpp/blob/master/xmpp.doap#L130
• XEP-0048: https://github.com/processone/xmpp/blob/master/xmpp.doap#L139
• XEP-0059: https://github.com/processone/xmpp/blob/master/xmpp.doap#L184
• XEP-0066: https://github.com/processone/xmpp/blob/master/xmpp.doap#L211
• XEP-0084: https://github.com/processone/xmpp/blob/master/xmpp.doap#L238
  ...
• XEP-0313: https://github.com/processone/xmpp/blob/master/xmpp.doap#L517
• XEP-0402: https://github.com/processone/xmpp/blob/master/xmpp.doap#L661
• XEP-0421: https://github.com/processone/xmpp/blob/master/xmpp.doap#L697
• XEP-0422: https://github.com/processone/xmpp/blob/master/xmpp.doap#L706
• XEP-0424: https://github.com/processone/xmpp/blob/master/xmpp.doap#L715
• XEP-0425: https://github.com/processone/xmpp/blob/master/xmpp.doap#L724
• XEP-0430: https://github.com/processone/xmpp/blob/master/xmpp.doap#L733

Thanks in advance.

In the past, when a new XEP was implemented, it was not annotated anywhere what XEP version was being implemented. Consequently, right now nobody knows or remembers which precise version is implemented.

Before the development task of upgrading the source code to support the latest XEP version, it is necessary to know what version is actually implemented.

Can you perform the investigation task of detecting what XEP version is actually implemented? It involves looking at the codec specification and comparing it with the different XEP versions:

When a relevant difference is detected between the codec spec and the XEP, and there is a clear relationship in the dates of the git commit and the XEP publication, this is a strong indication that this is the XEP version implemented. Can you investigate what XEP version is probably implemented, and indicate the reasons?
