Good point. That info probably should be in the doc. I'd have to research what the value is - 4096, I think... or 4095, perhaps: 4096 exactly has been reported buggy in some versions, IIRC. Honestly, I never tried a 4096-byte identifier to test it... seems like "enough" bytes are available... but there *is* some number that's maximum, and it *should* be documented.
Thanks for the suggestion!
Best,
Frank
