Extensions and error conditions

I was just wondering, how should an extension deal with error conditions.
Should an extension just throw an exception (assuming it's written in java)
or are there other mechanisms ?

As a simple example, suppose that the SQL extension where unable to reach
the database (something went wrong, for instance no Driver found on the
classpath), chances are the resulting xml file will contain rubbish. If
this were to happen during a sequence of stylesheet transformations, it
would be nice if Xalan could abort user code linking the sequence together.

I probably just overlooked something in the documentation

Cheers,
Erik
