for early versions of PHP 5 errors from libxml2 are emitted as PHP 
Warnings/Notices so you need to implement an error handler if you want 
to capture and handle them.
As of 5.1.0+, trappable structured errors were implemented. See: 
http://www.php.net/manual/en/function.libxml-use-internal-errors.php
This type of error handling can be used with any of the XML based 
extensions, not just DOM.
