Summary: XQ: misleading error msg for fn:resolve-QName
Initial Comment:
Hi all, I think the following error message is a bit misleading:
$ echo 'fn:resolve-QName("foo:test", <a xmlns:foo="bar"/>)' | pf
error in function application: at (1,1-1,50): wrong number of arguments for
function `fn:resolve-QName' (expected 1, got 2)
because the query itself is correct (according to the standard), and the error
is actually caused by that pathfinder implements a different signature than the
standard one.
So I have two suggestions:
- change the error message into: reference to undefined function
`fn:resolve-QName', which makes the code and the documentation
(http://monetdb.cwi.nl/projects/monetdb/XQuery/Documentation/QName-Functions.html)
matching each other
- since pathfinder supports a 'resolve-QName' function, with different
signature, maybe we should consider using the prefix 'pf', instead of 'fn'?
Regards,
Jennie

Jennie,
this is an artifact from Jens. fn:resolve-QName with one parameter
basically is a cast to xs:QName -- but have a look in
compiler/algebra/builtins.c for more information.

That is fine with me.
But how about the fn:resolve-QName with one argument? It's quite unclear
what it does.

Hi Jennie,
I added a signature for fn:resolve-QName with two arguments. The error
message now is: ``fatal error: Algebra implementation for function
`fn:resolve-QName' unknown.''
Can you live with that?
