Overview

Class containing an <item/> element

The ‘name’ attribute has been renamed to ‘iname’ here as ‘name’ is already used by REXML::Element for the element’s name. It’s still name=‘…’ in XML.

This is all a bit analoguous to Jabber::RosterItem, used by Jabber::IqQueryRoster. But this class lacks the subscription and ask attributes.
