vs 2008 javascript intellisense in XML file problem

I am trying to get javascript intellisense to work for jQuery in a .xml file. I've already used a custom XSD to provide intellisense for the XML. Under the tag, I have a mixture of HTML and javascript which are enclosed by . And it is all greyed out so no intellisense there.

Adding a /// does not help as well.

I would really like to be able to have intellisense when writing javascript in the XML file.

From stackoverflow

• I can either get javascript intellisense or xml intellisense working one at a time but not both together by adjusting Tools -> Options -> Text Editor -> File Extension.

  This makes me think that this should be tweakable more somewhere. The registry?

  This is a hot fix for java script intellisense that may help.

  seanlinmt : I had tried that before. It doesn't work. The .xml file extension seems to be lefted out.
