Can somebody gie me an example of something that is an "error", but not
"fatal"? At least during parsing, I thought that all errors were fatal.
And all of the errors I can think of from each of the xmlErrorDomain
(below) values looks fatal (except maybe some HTML things, if the
library was operating in a kind of tag soup mode).

Of course, that doesn't stop me (and others, apparently) from trying to
recover from errors inside error handlers and either continue parsing or
queue things up for a restart, but that is slightly different.

Nice. :-)
