grid from xml - Invalid XML when using total_count and pos

I am using dhtmlx Grid Pro and I have a grid which is configured and loaded from XML. It all works fine except when I add the total_count and pos attributes to the element, as I get Invalid XML error.

XML sample

<?xml version="1.0" encoding="iso-8859-1"?> StatusClosedIn Progress In Progress In Progress ...

Problem sorted - please ignore
