In 9.1 Saxon will retain column numbers as well; though I fear that this
will lead to false expectations. Certainly for reporting errors in schema
and stylesheet documents, it would be really nice to have accurate line and
column information for every attribute.

I don't really accept the arguments about attribute value normalization. I
think the real reason parsers (and APIs) don't provide more information is
an obsession with performance, not realizing that for many applications,
parser performance is not the #1 objective.
