>          Issue Type: Bug

> ODE adds a preamble to XQuery expressions prior to executing them. This 
> preamble includes the namespace declarations and external variable 
> declarations. I got a static analysis error saying that there was a duplicate 
> global variable declaration. I saw the following under the debugger:
> ...
> declare variable $SubmitRequestResponse.SubmitRequestResponse external ;
> declare variable $SubmitRequestResponse.SubmitRequestResponse external ;
> ...
> I modified the expression to map the global variable to a local variable and 
> use the local variable multiple times instead of referencing the global 
> variable multiple times. This only produced a single declaration for the 
> variable in the preamble and worked fine.
