XMERL - why fatal errors?

Hi,

The present version of xmerl does not distinguish between fatal errors 
and validation errors .
This is also commented in the User's Guide of xmerl.

Another error strategy is under development, but not entirely finished. 
With that strategy
it will continue parsing even though a minor error is encountered and 
return a parse/validation error as a tuple {error, Reason(s)}
