Relevant comment by Linus Torvalds on standards:
"I've said this before, and I'll say it again: a standards paper is
just so much toilet paper when it conflicts with reality. It has
absolutely _zero_ relevance. In fact, I'll take real toilet paper over
standards any day, because at least that way I won't have splinters
and ink up my arse."

Ah Linus - enough said. The UMF spec wasn't intended to be a standards paper. You might be able to tell it isn't formatted as such. Based on the comments in this post - it has at the very least helped spark interesting feedback and debate.
