PEP event notifications 'item' not 'items'?

I think that when server sends event messages to subscribers there should be an items node not item. If my memory isn’t failing then the ‘items’ way is defined in XEP-0060. Is this a bug or am i missing sth?

<message xmlns=“jabber:client” from=“xxx@domain” to=“yyy@domain/Home” id=“”>

<event xmlns=“”>

<item node=“”>

<item id=“current”>

<mood xmlns=“”>

<offended />
