[news.eclipse.webtools] Changing plugin from custom to xml file extensio

["Axel Gallus" <uh5d@xxxxxxxxxxxxxxxxxxx>]

Hi, i wrote a plugin for a new xml based filetype called mdl2e.
The plugin introduces a own validation, syntax highlighting, and filetype.

I now want to apply the same plugin for normal *.xml files.
I tried to change   file-extensions="mdl2e" in   file-extensions="xml"
 in the contentTypes extension point as well as in the  validator,
but the new syntax highlighting and validation don't work if the file has  a 
*.xml extension.
Can someone tell what I have to change in my plugin.xml to get it work with 
normal xml files?
