That's about what I was expecting. :)

... which is not currently accessible by itself.

>From my POV, you would normally use the "error_log" property of the thing you
are working with (XSLT, RelaxNG, XPath, ...) rather than the exception. The
only case where it is interesting to access the log through the exception
would be the instantiation of such an object. And here, I don't think you'd be
interested in anything but the cause of the problem.

So, guess I'll just change it in general and make it another beta. :)
