My preliminary thinking is that Exiv2 will use these just like the 
existing tag lists. Exiv2 XMP key strings would then be 

"Xmp.exif.ApertureValue", "Xmp.iptcCore.CountryCode" 
or "Xmp.photoshop.Category" etc.

Or are there more levels than namespace and tag name? i.e., can XML 
namespaces be nested?
