If SPACEJUMP and TEXTSEARCH are attributes of an object and not 
methods --- what are we going to do if we move from URLs to URNs?
Then every URN is an object with an associated attribute.
Will there be different URNs for "get me a document" and 
"search in a document"?

Can a server disambiguate this:

	GET /12345?....

"12345" is an URN, not a path to an object.
