The existing text describes the behavior pretty well:

5.     Function tracing is  enabled:  command  substitu-
       tion, shell functions, and subshells invoked with
       ( command ) inherit the DEBUG and RETURN traps.
6.     Error tracing is enabled:  command  substitution,
       shell  functions,  and  subshells  invoked with (
       command ) inherit the ERR trap.

To be clear, you're suggesting that I add something to the `extdebug'
section to explain how these features can be enabled separately from
`extdebug'?
