Ampersand in xml url is not passed through

Hi,

This may be a known fact, but I did not manage to find it with Google.

I generate my xml on the fly from database content.
So I embed the viewer like this:

<script>
  var viewer = createPanoViewer({swf:"mypath/krpano.swf", target:"pano"});
  viewer.addVariable("xml", "mypath/krpano-xml-generator.php?scene=amsterdam1&country=holland");
  viewer.embed();
</script>

Trouble is: krpano only requests the part up to the ampersand from the web server: mypath/krpano-xml-generator.php?scene=amsterdam1
I had to resort to mod_rewrite and replace the ampersand with something like "....."

Regards,
Serge.
