formats available for controller

Hello,

I was wondering if there is any way to retrieve the list of formats defined in the respond_to block of a controller?

For example if the following is in a controller:

    respond_to do |format|       format.html       format.xml { render :xml => @people.to_xml }     end

Is there a way to find out HTML and XML are available? I want to write a method that creates an XML list of all formats available for any given controller.

Cheers, Stephanie
