Notes on the Saxon implementation
Saxon allows the first argument to be an empty sequence, treating this as equivalent to
calling fn:error()
with no arguments. The error code (local part and
namespace URI part) is recorded as part of the exception that's supplied to a user-defined
JAXP ErrorListener
, or that is returned to the calling application. The value
of the $description
is available by calling getMessage()
on the
Exception
object. The error details are also available to the
catch
part of a call when using the XQuery 3.0 or XSLT 3.0 try/catch
construct.
