Re: [bdbxml] Passing a list to XmlQueryContext::setVariableValue

This is not currently possible using the C++ API, but it is something 
that we are looking at implementing. Would this be of use to you?

You can work around this restriction by doing this:

declare variable $a as xs:string external;
declare variable $b as xs:string external;
declare variable $dtToGet as xs:string* := ($a, $b);

...

And then set variables "a" and "b" in the XmlQueryContext.

I hope this helps,

John
