Equality for decorated intervals

[dpsanders]

Currently we have

julia> DecoratedInterval(1..2, com) ==  DecoratedInterval(1..2, trv)
true

Is this specified in the standard?

According to section 11.5.3 of the standard, "For decorations, comparison operations for equality = and its negation shall be provided, as well as comparisons >,<,≥,≤ with respect to the propagation order (com > dac > def > trv > ill)"

But we also have this test in the ITF1788 suite,
@test ==(DecoratedInterval(Interval(1.0, 2.0), def), DecoratedInterval(Interval(1.0, 2.0), trv))
which is expecting a True answer(even though the decoration is different).

I understand that statement from the standard as referring only to decorations, not to decorated intervals.

I think we should follow the behaviour of the octave interval package here.

In the test suite we have,
DecoratedInterval(2, 1) == nai() == true
but
nai() == nai() == false
Aren't they contradicting?
