Vista - How to have intellisense when editing a custom-formatted XML?

[Subj] How to have intellisense when editing a custom-formatted XML?

Hi,

I created a xml file which I use as a custom configuration file, I
have it as content file in my project
I generated for it the XDS with xsd.exe, and I would like to use it to
have intellisense available when I edit the xml file (or other xml
files that follow the same format)
What should I do to have VS reference my generated XSD to offer
intellisense when I edit the XML?

Thank you
