There's undefined behavior, which is quite well specified. What do you mean by unspecified behavior? Do you have an example?

Undefined is absolutely clear in the spec.

Unspecified is whatever you want it to mean. I am also laughing, having never heard "unspecified" before.

Unspecified behaviour is defined in the glossary at the start of the spec and the term "unspecified" appears over a hundred times...
