Confusing: repetition of requirements for SC at different levels
Question: Does complying with an SC at L1 automatically leads to compliance
of an SC at L2?
Example: When audio descriptions for a video are provided (SC1.2.2) then SC
1.2.3 is also being complied with simultaneously, is it not?
In this context what is the difference between  'minimum level' and
'enhanced level' of accessibility? In what context ? Who decides if it is
minimum or enhanced?  (see my earlier post on this topic)
In the understanding WCAG 2.0 doc there are no distinctions highlighted
between 1.2.2 and 1.2.3 as far as audio descriptions and level of
accessibility are concerned.
Conversely, why is not the SC at L1 for GL 1.1 also listed at L2?

Proposal: Do not repeat  requirements at L2  if they are already listed at
L1 for a guideline; and do not repeat at L3 what is already stated at L1 or
L2 for a guideline.  
Signed language interpretation is required only at L3 for 1.2 and this is
not repeated at L1 or L2. This is how it should be.
