RE: [XQuery]&[F&O] fn:error: function parameters

I'm not sure what product you are referring to here.
 
Saxon 8.1 still implements the November 2003 version of the error()
function, which takes a single argument of type item(): see

Hi Michael,
I am wondering whether you would really achieve the desired results.
>error("No input")
when you give an input in XQuery as fn:error("No Input")
At my end I am getting the exception thrown as 
javax.ejb.EJBException: System error: {err}XP0004: Invalid static type:
{http://www.w3.org/2001/XMLSchema}string.

This is not as per you mention in your mail. What could be the reason for
the difference in nature of error thrown? 

However I too agree that it would be much better to change the
'Unidentified Error' to  'User Error'. 

Regards,

Kanad.
