[plt-scheme] 'net/url' package: path/param?

Hello,

I'm learning the 'net/url' package:

http://docs.plt-scheme.org/net/url.html

I don't understand how to create a 'path/param':

http://docs.plt-scheme.org/net/url.html#(def._((lib._net/url-structs..ss)._path/param))

since parameters are already passed by the 'query' argument to the
'url''s constructor:

http://docs.plt-scheme.org/net/url.html#(def._((lib._net/url-structs..ss)._url))

therefore I should only pass path's components.


Thanks
