Ok, I see that, but I don't see why you'd want to then use absolute
references in the widget content.  Is it your intention that widget
authors would have knowledge of the base URI (or the algorithm)?  From
my POV, you'd want them authoring links to other widget parts using
only relative references, like ZIP and all other packaging formats I
know of do (at least those supporting hierarchical containment).

Or just http://localhost/theFooEngine/barWidget.wgt/index.html#welcome ?
