If the 'lr' parameter has a value assignment, is UA B truly justified in 
ignoring the route set categorically?

Or is that one of those things where behaviour for improperly formed tokens is

The latter.

You could have various kinds of implementations:

- strict ones, that reject the message as ill-formed
- forgiving ones, that try to keep things going as best they can
  in the face of errors (perceived or real)
- naive implementations, that work ok for well formed messages,
  but that assume messages are well formed and fail to even notice
  certain kinds of mistakes and act in ways that depend on
  the random idiosyncrasies of their implementation.
