Throwing exceptions in Xalan Java extension functions

["Karr, David" <da...@wamu.net>]

In a Java extension function, what is reasonable to do if the code
throws an exception?It's easy enough to add a catch block and do nothing
with it, or log it in an application-specific log, but is there
something appropriate that should be done knowing that it's a Xalan Java
extension function?  Is there an appropriate wrapper exception I should
be throwing?
