ありませんと - possible interpretations


My understanding of ありませんと is that it is an abbreviated form of
ありませんと(だめ/いけない/ならない), but the formal ません throws me off. I was under the
impression that the formal part should be always the last one, so it should be
ないと(だめです/いけません/なりません). Is it possible that abbreviation moves the formality
before と? Are the following interpretations possible?

> ... must be
>
> ... must have something




It would help to know the context, and I'm not confident with this answer, but
here goes. You may know that ～ないと, ～なくては（なくちゃ）, and ～なければ（なきゃ）are often used
as shorthand for ～ないとだめ et cetera. In ありませんと, ～ませんと basically acts as
shorthand for ～ないとだめです - being explicitly polite while still cutting off the
ending.

Also, you really should know this, but the negative of ある is simply ない, not
あらない or anything.
