[basex-talk] Passing an array to REST HTTP service

Hi I'm wondering if this is at all possible... I defined an array variable in my XQUERY: declare variable $ca as array(xs:integer) external := []; How can I assign a value (e.g [1,2]) to this variable through the URL? I have already tried: http://host:port/rest/dbname?run=query.xq&$ca[]=1&$ca[]=2 That didn't work. Neither did this: http://host:port/rest/dbname?run=query.xq&$ca=1,2 Any hints are much appreciated. Thanks Csaba
