Subject: Return an empty <vCard/> element in an IQ-result when no vCard exists.
X-Git-Tag: 14.12~28^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=94cdcd7b34ccc83acfb32be09016cb7859d20916;p=ejabberd

Return an empty <vCard/> element in an IQ-result when no vCard exists.

According to XEP-0054, if no vCard exists, the server MUST return a stanza
error (which SHOULD be <item-not-found/>) or an IQ-result containing an
empty <vCard/> element.
