  Please remember that XPointer was defined in tandem with XLink to 
improve document hypertext on an XML based Web. And since attributes
are not displayed I don't think pointing within attrubutes was really
a requirement from our charter point of view. But that's true for 
comments content too ... So I'm not 100% sure about XPointer and
attribute content selection, sorry.
