+1. With the additional free suggestion that the line and column number
be reflected in attributes:

  <message line="1" column="2"
           position="line 1, position 2">Parsing failed</message>

I don’t feel strongly about whether @line/@column should replace
@position or be in addition to it. But don’t make me micorparse the
@position attribute to position the cursor in Emacs, please :-)

An option to produce output that’s in a form consistent with C and other
parsers, might be nice too:

  filename:1:2:Parsing failed. Permitted at this position…

                                        Be seeing you,
                                          norm
