The tag standards came up (currently only 3 questions).
I think we don’t need it.
It’s not an attribute/feature of a software, not even a use case I guess, but only something merely related to a goal (but even then it’s not clear what it really means).
If the goal is testing for (technical) standards compliance, validation could be used, I guess.
If a software has to follow some standards, it should be sufficient to state it in the question.
