Motion 44: YES
I vote YES on Motion 44, but think that the wording could be better:
There is an apparent contradiction between the first and the last
sentence of the second paragraph since the empty set is a value.
I would rephrase this paragraph in a more concise way as follows
(where /.../ means italic, normally used to define the term, so
that "is said to" is redundant):
The operation nums2interval(l,u), where l and u are extended-real
values, /succeeds/ and returns the non-empty interval
[l,u] = { x in R | l <= x <= u } if (see §9.2) the conditions
l <= u, l < +inf and u > -inf hold. Otherwise the operation /fails/
and returns no value.
Similarly, I would rephrase the last line "Optional rules for [...]"
with "and may optionally be followed" removed:
Optional rules for the string t accepted at an implementation level
are given in the Level 2 Subclause 11.11.1 on interval literals.
