Under no circumstances should '/base' + 'relative.xml' == '/base/relative.xml'.
It would only be an acceptable result if you had '/base/' instead of '/base'.

Same here. This is incorrect.

(1) 'file:plans.xml' is not a relative URI reference.
(2) The result of merging the reference 'file:plans.xml' with *any* base URI
must be 'file:plans.xml'. RFC 3986 sec. 5 governs this resolution.

Trust me, you'll find that it is much easier to implement RFC 3986 sec. 5 than
it is to work around bugs in urllib and urlparse. I suggest porting Absolutize()
and BaseJoin() from 4Suite's Ft.Lib.Uri.
