[Exist-open] RESTXQ error with variable declaration

Hi Adam, I get a "err:XPDY0002 variable '...' is not set" error when I use RESTXQ URL to execute a module that declares variables. Below is a module [1] that causes the error [2]: Once I store this module in the db, I would expect the following results when I call the function in my browser via http://localhost:8080/exist/restxq/test: <hello>world</hello> Instead, I get the error below. The syntax I use above for declaring variables is described in the XQuery spec at http://www.w3.org/TR/xquery/#id-variable-declarations (and http://www.w3.org/TR/xquery-30/#id-variable-declarations for XQuery 3.0). Thanks, Joe [1] module: /db/test.xql xquery version "3.0"; module namespace test="http://exist-db.org/restxq/test"; declare variable $test:hello := element hello {'world'} declare %rest:GET %rest:path("/test") function test:test() { $test:hello }; [2] error from exist.log 2012-08-31 16:51:05,598 [eXistThread-43] ERROR (RestXqServlet.java [service]:110) - err:XPDY0002 variable '$test:hello' is not set.
