Looking at draft-dold-payto-04, I see the BNF:

     opts = opt *( "&amp;" opt )

I suspect that "&amp;" is a remainder from some conversion process, and
you intend "&".

Also, in:

     opt = (generic-opt / authority-specific-opt) "=" *( pchar )

note that "&" is admissible in pchar because "&" is in sub-delims, which
makes parsing an opts difficult.  (Annoyingly, the current IETF BNF
doesn't seem to have a simple way of saying "a pchar that is not &".)
