That's possible, and has the advantage of offering the next software 
layer a uniform representation of tags. On the other hand, it then 
means that private-tag purists have to be aware of the extra prefix, 
which is only there for URI compatibility. A Python fan might expect 
!graphix.shapes.Square to map directly to package graphix.shapes and 
class name Square, and be annoyed at having to strip off the 
tag:yaml.org,2002:private/ prefix first... Especially since all this 
prefix signifies is that there is no prefix... :-)

Strictly speaking, tags URIs are not hierarchical in that way, so ../ 
is meaningless -- that's why we have to define our cooking process 
ourselves, rather than talking in terms of relative URI references and 
base URIs and all that jazz.

It's also why I personally prefer to avoid slashes in tag URIs (even 
though they do no actual harm so long as you know they are not special 
characters in non-hierarchical URIs).

Finally, !!int has the advantage that it *always* refers to 
tag:yaml.org,2002:int, even if a default prefix is defined.
