The subject draft states:

   The ABNF for URI and URI-reference has been redesigned to make them
   more friendly to LALR parsers and reduce complexity.

However, attempting to use that ABNF with an LALR parser yielded
literally hundreds of shift/reduce and (more importantly)
reduce/reduce conflicts.  A GLR parser was fare any better with the
ABNF.

Are there any implementations using the ABNF as specified in the draft?
