Design Guidelines (naming of event listeners mainly)

Is there an ‘official’ document with guidelines for writing actionscript 3? I’m looking specifically for naming guidelines.

Some examples could be, pascal or camelcasing, underscores for private fields, function naming, using _txt and _mc (to trigger hints in the Flash CS3 editor mainly), naming of event listeners etc.

If there is not such a reference, what are your preferences?

Thank you!
