Microsoft WSE 2 0 SP2 msi Problem

When I installed WSE 2.0 SP2 and called Wse WEB Service function with
DataSet as a parameter, I've got the following exception (non-WSE call is
Okay) :

System.SystemException  {"Server was unable to read request.  --> There is
an error in XML document (1, 4321).  --> The
'http://tempuri.org/:Package_Constraint1' identity constraint is not
declared.  An error occurred at , (1, 3905)."}

The DataSet is result of .Net GetChanges function and looks like this:

<?xml version="1.0" standalone="yes"?>

I discovered that

msdata:ConstraintName="Constraint1"

is always missing in between

<xs:unique name="Request_Constraint1"

and

msdata:PrimaryKey="true">

if a table is the first in DataSet Tables list.

For example, I've changed the order of Table list from previous example and
set PackageApproval table to be first, instead of Request:

<?xml version="1.0" standalone="yes"?>
<NewDataSet>
 <xs:schema id="NewDataSet" xmlns=""
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
   <xs:element name="NewDataSet" msdata:IsDataSet="true"
msdata:Locale="en-CA">
     <xs:complexType>
       <xs:choice maxOccurs="unbounded">
         <xs:element name="PackageApproval">

....

     <xs:unique name="Constraint1" msdata:PrimaryKey="true">
       <xs:selector xpath=".//PackageApproval" />
       <xs:field xpath="PackageID" />
       <xs:field xpath="UserID" />
     </xs:unique>

...

     <xs:unique name="Request_Constraint1"
msdata:ConstraintName="Constraint1" msdata:PrimaryKey="true">
       <xs:selector xpath=".//Request" />
       <xs:field xpath="RequestID" />
     </xs:unique>
