1284	Confusing language in profile definitions (A.3.1)	fbossen		"A.3.1 says:
Conformance of a bitstream to the Main 10 profile is indicated by general_profile_idc being equal to 1.
Conformance of a bitstream to the Main 10 Still Picture profile is indicated by general_profile_idc being equal to 65.
 
It also says:
–	In a bitstream conforming to the Main 10 profile that do not conform to the Main 10 Still Picture profile, general_level_idc and sublayer_level_idc[ i ] for all values of i in the referenced VPS (when available) and in the referenced SPSs shall not be equal to 255 (which indicates level 15.5).

The qualifier ""that do not conform to the Main 10 Still Picture profile"" is somewhat confusing here, since it seems impossible for it to be false (general_profile_idc may only take one value), although the following note seems to imply otherwise:
NOTE – When the conformance of a bitstream to the Main 10 Still Picture profile is indicated by general_profile_idc being equal to 65, and the indicated level is not level 15.5, the conditions for indication of the conformance of the bitstream to the Main 10 profile are also fulfilled.

What are we trying to say here?
