Bitstream conformance problem for IRAP pictures in HEVC version 1

Description

In C.4 one of the conditions for bitstream conformance states:

"8. For each current picture, the value of maxPicOrderCnt − minPicOrderCnt shall be less than MaxPicOrderCntLsb / 2."

Shouldn't it rather be:

"8. For each current picture that is not an IRAP picture with NoRaslOutputFlag equal to 1, the value of maxPicOrderCnt − minPicOrderCnt shall be less than MaxPicOrderCntLsb / 2."

Both the current picture and the previous picture in decoding order that has TemporalId equal to 0 and that is not a RASL picture, a RADL picture, or a sub-layer non-reference picture, are included in the set of pictures from which maxPicOrderCnt and minPicOrderCnt are calulated.

IRAP picture with NoRaslOutputFlag equal to 1 has POC msb equal to 0 which makes it difficult to fulfill the above condition.
