Handling errors in PyXML/SAX

[Matt Gerrans]

I don't know the exact answer, but based on a quick look:

Look at the " validate_attributes() member of ValidatingApp, on line 201 of
xmlval.py ("self.parser.report_error(2006,attr)"), in the xml directory
under the python directory.  That is where it is printing the message, using
the string 2006 from the localization dictionary in errors.py.   You'll have
to dig a little deeper to find out what the (poorly named) attrs variable
is, but seems it is a list of filenames, from which "Unknown" is coming.
Maybe it is a bug that it shows Unknown instead of the filename.
