Description
In section 7.4.3.18, there is conformance for alf_luma_clip_idx and alf_chroma_clip_idx as below:
It is a requirement of bitstream conformance that the values of alf_luma_clip_idx[ sfIdx ][ j ] with sfIdx = 0..alf_luma_num_filters_signalled_minus1 and j = 0..11 shall be in the range of 0 to 3, inclusive.
It is a requirement of bitstream conformance that the values of alf_chroma_clip_idx[ altIdx ][ j ] with altIdx = 0..alf_chroma_num_alt_filters_minus1, j = 0..5 shall be in the range of 0 to 3, inclusive.
Since the syntax elements are coded with u(2), the conformance (SEs shall be in the range of 0 to 3) is unnecessary.

Good catch, thanks! Will be fixed (by removing the two constraints) in JVET-S2001-vE.
