How do you determine supported operations for a service in code?

Question

When I look at the REST url for a service it tells me (at the bottom) the list of supported operations for that service, e.g., Export Map, Identify, Generate KML, etc.  Is there a way in code to determine what the supported operations are on a map service layer.  My problem is that some services have "Identify" and some do not.  I do not need to call an Identify operation for a layer that doesn't support this.  Furthermore, within that service some of the layers have "Query" capabilities and some do not.  I would like to be able to determine this via code.  Can I do this?
Thanks!

Deona, Here is a working example of how to get the supported services as Mehul eludes to. This will work until the final release as Keyur mentions.

We'll be adding a "capabilities" property to the JSON response at final. It will be a comma-separated string whose value will be something like "Map,Query".

Map => export map supported
Query => find and identify supported

The api does not have explicit property/method to list supported operations for REST service. however,
ypu can make a HTTP call to the REST url for a service with f=json and use JSON.decode method of the api to get the flex object from which you can get the info about the supported operations.
