anyURI mystery help

[<santony@bellsouth.net>]

I did spend some 2 hours trying to solve this problem with google, without any result.

 I have the following simple xml file
<?xml version="1.0" encoding="UTF-8"?>
<message xmlns:idm="http://www.bellsouth.com/idm";  
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns="http://www.bellsouth.com/idm";
xsi:schemaLocation="http://www.bellsouth.com/idm file://wherever_schema_is_stored/NMS-LESYG-IF_WFAC_ALL.xsd"
system="DSLNMS" systemInstance="WFAC" cuid="WfacIDM"
messageID="CYJEFF69-1115748309103000" clientID="jbbos" priority="1" timeToLive="0">
<responsePayload>
<returnStatus>Success</returnStatus>
</responsePayload>
</message>

But when I try to validate this file against a schema, I get the error that  "file://wherever_schema_is_stored/NMS-LESYG-IF_WFAC_ALL.xsd  is not valid anyURI".
( Im using xerces by the way. with JDK 1.4 )
