functions can return sequences to xcc.
try this as a simple example and build on
declare function module:test()
{
[ 1 to 10 ] , "HI" , <node/>
}

Subject: Re: [MarkLogic Dev General] Retrieving file name/document URI of
binary content
Yes it does in an .xqy page or in query console.
Now I am trying to get it to work inside XCC Java code but it does not work as
it is in AdhocQuery class.
Can we get multiple results out from a module which has this piece of code?
Function can return just single value so that may not work in this case?
Thanks
