Thank you for your list.  I've search those also.  Let me give you a quick example where I actually found the option but the docs don't supply any additional information.

I believe I need to create new VM profiles since I'm running multi-tenant.  I figured that one out by looking at other commands that expect a voicemail_profile value.  In searching through the default profile I found the parameter "callback-context."  Since "context" is generally used in FS in connection with multi-tenant I assume (perhaps incorrectly) that this is important for me.  So, I go in search of the parameter in the docs.  And, after much searching (I have gotten better at this over time) I find:

callback-context

default

     <param name="callback-context" value="default"/>
