WCAG 2 isn't clear on this. On the one hand it says in 5.1 (https://www.w3.org/TR/WCAG21/#interpreting-normative-requirements) that the introduction, appendices, examples and all sections marked as "non-normative" aren't normative. That doesn't include the guidelines and principles, so in that respect those two are normative.

Unfortunately there is a second interpretation possible. If you look at the definition of "normative" it says "required for conformance". If you then look up what is required for conformance, it only includes the success criteria. Not the principles or guidelines (not even the conformance section itself).

It's a little weird. I've always just pretended that "normative" definition doesn't exist. What is and isn't normative has nothing to do with if something conformance or not.
