Single quotes in system tags, specifically the use of ' in the href line in <!-- System:CountDown -->, keeps me from embedding the tags in a javascript variable. I'm doing this to make a scrolling marquee that is cross-browser compatible.
Since it doesn't change the ability to fire the javascript code to pull up the calendar, could you please change the template for this to use double quotes around the href tag? It didn't break anything in IE nor Firefox when I tested it, and also doesn't break the HTML compliance.
