By the way, I'm not convinced that a single generic error handler is
such a good idea. May be we can classify the type of error to make the
handlers a little less generic but more 'typed'. For example 'file' and
'line' attributes seem to be relevant only in the context of file
parsing. What about xpath syntax errors (say) ? Or (I'm coming from C++,
you'll notice) stream based input, i.e. when there is no notion of 'file
name' ?

I think the approach to capture all that in a single generic handler is
fundamentally flawed.
