The current version of UTN #6 is simply the last version of it that
was published before the proposed draft UTS #40. When the UTC decided
to withdraw UTS #40, there was nothing automatic to move the text
improvements to the UTN.
I will try to find some time sometime soon to merge the text
improvements that I made for PD-UTS #40 into the format of the UTN.

I didn't mean to ask for what the purpose of BOCU-1 was. I was just
curious about where someone felt that one of "my babies" was useful to

I didn't say that, and I don't think that.

Both UTN #6 and PD-UTS #40 specify the very same algorithm, which is a
profile of the general BOCU.

I am not a lawyer and plead complete ignorance on legal issues. My
_understanding_ is that when using ICU, the use of everything in ICU
is covered by the ICU license, while when implementing BOCU-1
independently, the terms in UTN #6 apply.

This will get fixed when I get around to roll the text improvements
from PD-UTS #40 into a new version of UTN #6.
