The items i put into my robot dont have a date-string.

I would like to work around this problem by using the <guid>-tag for rss2.0 to give each item a unique id so my reader can understand which one it is.

Unfortunatelly I cannot do this since the rss-model doesnt support the GUID-field.

Can it be extendet?

Regards 

PS: See wikipedia for more information about GUID "<guid>Eindeutige Nummer des Artikels, muss für jeden Eintrag anders sein</guid>" http://de.wikipedia.org/wiki/Rss
