Right a few questions for the Oracle gurus;

Does Oracle or a thrid party support OPC (http://www.opcfoundation.org/)? If so does anyone have any comments about it? I have asked my tutor (who happens to be the Oralce DBA of the year - apparently - but he wasn't sure).

How easy is it to get Oracle to take XML as an input and get it into tables? Is this slow/fast/bad/etc?
