Why not? Seriously, I can see a case where this could be useful: if
you want to write some software that takes as input an ABNF grammar, I
think it is easier to parse the XML (mainly because there are
libraries ready off-the-shelf to do this) than the raw ABNF.  I agree
that the procedure would turn out a bit convoluted....
