Just playing around and exposed an OData endpoint in a .net domainservice.

I can browse to the link in IE9 but instead of showing the underlying XML it displays a Feed page.
The page shows that the correct number of entities have been retrieved and shows the equivalent number of empty slots but no data.
If I 'View Source' I can see the expected xml with all entities listed.

How do I get IE9 to just display the XML ?
