Is it possible to hide certain functions/fields from displaying in javascript intellisense drop down list in Visual Studio 2008? Either by javascript documentaion XML of by naming privates in a certain way?

I've seen <private /> in jquery vsdoc file that implies exactly this behaviour, but doesn't meet my expectations

{
    __hiddenField: 0,
    /// <private />
    increment: function(){
        /// <summary>Increments a private variable</summary>
        __hiddenField++;
    }
}

But since fields can't contain documentation (because they have no body) they have to be documented at the top. But still doesn't work:

{
    /// <field name="__hiddenField" type="Number" private="true">PRIVATE USE</field>
    __hiddenField: 0,
    increment: function(){
        /// <summary>Increments a private variable</summary>
        __hiddenField++;
    }
}

Impossible is a perfectly possible answer and will be accepted if you have the knowledge that it's actually not possible.
