Typo in section 3.6.3?

[phill-williams]

The last line of 3.6.3 reads:

The Centre (or Front Centre) channel comes first and is followed by the LFE (or LFE1) channel, and then the L channel.

Obviously the L channel (front left) should not come after LFE.

Is it meant to be LFE2? But in that case would LFE2 be coupled with LFE1?

@phill-williams, thanks for the comment.

Let me explain the background.

It is for scalable audio. For example, 2-layer scalable audio, 5.1ch/Mono.
In this case, the first Channel Group consists of 5chs (1 coupled substream and 3 non-coupled substreams: Ls/Rs, C, LFE, and L), and the second Channel Group consists of a Mono channel that is mixed from the C, L, R, Ls, and Rs based on the rule defined in figure 6.

The section 3.6.3 describes the channel orders in a Channel Group, including this case.
