To what purpose would one wish to have software automatically parse 
out the hierarchical levels of a non-URL URI?  Even with URLs, with 
their specified hierarchy, you can't always reach a useful resource 
by simply paring off levels from the hierarchy, though users 
sometimes try it in their attempts to get around sites with poor 
navigation structures.  (There's a Bugzilla entry for the Mozilla 
browser that suggests adding an "Up" button that does this hierarchy 
slicing, with much debate over whether this is desirable or not -- 
many seem to think power users will find it useful but novices will 
get too confused.)  While this has some (intermittent) utility for 
URL navigation, what purpose would it serve for other URI types?

In general, I'd like to see more detailed description in the 
proposals for new URI schemes and URN namespaces of just what 
purposes these schemes can be used for.  There are lots of intriguing 
ideas for namespaces in these proposals, but they tend to be rather 
light on specifics about just what practical use they are.  Some 
concrete examples of uses to which they may be put would be helpful.
