flac dev - Jan 2014 - Exact FLAC subset constraints

Finally, does this mean that:

1. Now any block size from interval [16, 4607] is subset, e.g. 588?
2. Now any block size from interval [16, 16384] is subset, (only) if
sample rate > 48 kHz?
And the third is the most interesting question:
3. Now not only constant (fixed) block size stream can be subset,
variable block size stream can also be subset, (only) if minimum block
size of this stream >= 16 and maximum block size of this stream <=4607
(or <=16384 (only) if sample rate > 48 kHz)?

If answer on any of these questions is "yes", documentation on the
website should be updated (fixed)!

Please answer each of these 3 questions.

Thanks in advance!

No one here knows for sure, as Josh won't probably be listening 
to answer these questions, so I guess most of us are actually 
relying on the documentation that should be fixed. Anyway, the 
documentation lvqcl found indicated that the answer to your 
first two questions is in fact 'yes'.

I don't know why your third question is the most 'interesting', 
because as far as I know the website states nowhere that 
variable blocksize streams are not subset. It's simply not 
mentioned anywhere. However, be aware that the FLAC reference 
encoder always produces streams with fixed-size blocks, so most 
3rd-party (hardware) implementations, even the FLAC reference 
decoder, hasn't been tested with those variable blocksize 
streams. Therefore, it needs a bit of thought and testing to 
implement this. Probably that's the reason that the flake 
encoder says variable blocksizes are non-subset while as far as 
I know they technically aren't.

So I think the answer to the third question is yes, but please 
proceed with caution.
