Are we okay with replacing the MUST in "care must be taken to discard (filter out) the high-frequency information" by a a SHOULD? Filtering high frequencies out of a square wave used as a 8Hz LFO is certainly a reasonable exception, in the sense of the SHOULD of rfc2119.

I'd say making sure frequencies above Nyquist aren't folding back in the audible range should be required for a conforming implementation, since not doing so makes a _very_ noticeable difference.
