Notation \compoundMeter isn't documented

Hello, thanks for those examples that is perfect.

However, because I am curious (and don't a thing about this special  
notation) can you tell me why

\relative c' {
  \compoundMeter #'((1 4) (3 8 4))
  \repeat unfold 5 c8 \repeat unfold 10 c16
}

\relative c' {
  \compoundMeter #'((2) (3 8 4))
  \repeat unfold 5 c8 \repeat unfold 10 c16
}

Fails? and why I get a different error for each case?

Id kind of expect

\compoundMeter #'((2) (3 8 4))

to be equiv of     2
               3 + 8 + 4

Is this not allowed in music?

Or at the very least 2 + 2 + 2
                     3   8   4

Maybe this is an enhancement?

Again as an example

  \compoundMeter #'((1 4) (3 8 4))

could be the same as 1 + 4 + 4
                     3   8   4

I hope this makes sense?

I just want to know what the limitations there are and if these are  
@knownissues or bugs or something else I need to document.
