Minor Description
When the gadget XML is rendered with content rewriting enabled, all <script type="text/os-template"> are turned into <script type="text/javascript">. In fact, any script tag's @type attribute will be changed to "text/javascript" (this is added if no @type exists in the original XML).
This is problematic. The Opensocial Template spec (http://wiki.opensocial-templates.org/index.php?title=OpenSocial_Templating#Template_Format) calls for the wrapping of templates in <script type="text/os-template"> .. </script> tags. Currently, the only way to get this to work in shindig is to disable content rewriting entirely, which is obviously problematic.
It seems like the correct behavior would be for the content rewriter to leave the @type attribute as is, only setting it to "text/javascript" if it's missing.
