[Standards] XEP-0013: Flexible Offline Message Retrieval missing "purge" and "fetch" in XML Schema

[Christian Schudt]

Hi,

I am just implementing XEP-0013: Flexible Offline Message Retrieval and found 
that the "purge" and "fetch" elements are missing in the XML Schema.

Just saying, if anyone cares and wants to correct the XEP.
