You are the expert here, so I'll have to trust your judgment.
(I am certainly not going to mess with the dynamic implementation.)
I didn't see much difference between allowing prefixes
$dynamic_2014$ and $dynamic_14$ for format dynamic_2014 and allowing
$dynamic_33$ and $NT$ for dynamic_33.
OK, $NT$ doesn't have the word "dynamic" in it.
But otherwise: Except the prefix, dynamic_33 and NT hashes look exactly
the same.
So I didn't see any need to call NT's valid() function from within
dynamic...
The only difference to your implementation idea is this:
Instead of
1. the actual dyna number for the format.
2. an 'optional' array of dyna numbers which also can be processed by
this format.
3. the canonical number (i.e. number that gets written to the .pot file).
You'll have
1. the actual prefix string for the format.
2. an 'optional' array of prefixes which also can be processed by this
format.
3. the canonical prefix (i.e. prefix that gets written to the .pot file).
So instead of numbers (integers), you work with strings.
Doesn't sound too complicated to me.
