- For consistency, "<channel>" should, if possible, be chosen from
the list of main channels: R/G/B/A/Z/Y/RY/BY. This works for layers
that represent colors. Writers should be strict about using the
recommended channel suffixes,
but readers should recognize other reasonable versions, like r/g/b/a,
red/green/blue/alpha, etc..
This is what I was hoping to avoid in my code but cannot. Obviously
if you throw non-english languages possibly represented as UTF-8 or
possibly transliterated to ASCII in the mix you've got a lot of
permutations to deal with.
I think nuke's behavior is ideal with regard to layer/channel naming.
Another possibility is to define a header attribute that provides
semantic information.
