If a feature is required by the widget, and it isn't available for any  
reason (including an invalid IRI) then its reasonable for the UA to  
assume this Widget just won't work and reject it. It may simply be a  
typo, e.g.:

<feature name="http;//bondi.omtp.org/api/camera.capture"  
required="true"/>
                                     ^ typo!

I don't think it would be useful for this to silently fail.
