Hmmm, so shouldn't the minimum value be at least the lower bounds of "job-k-octets-supported"?

We could leave it as-is but since this is a v2.0 I'm going to simplify it.

Ah, right!

That's what I started to wonder after hitting "Send".
OK, I'll reword and make it clear that the tags aren't visible, unless there is a way to encode the naturalLanguage portion of a textWithLanguage value in PAPI?
