I agree with Ottselspy25 in their first post.

NOTDWU is a somewhat counter-intuitive name for a prefix / template.

I also agree that Doctor Who Universe is a term that's used elsewhere synonymous with "Doctor Who canon" and using the NOTDWU could be confusing for new users and could lead people to look for DWU to work out the difference. And while the Doctor Who universe page is fine in itself, it doesn't really explain the difference between what we do on this wiki and the Doctor Who universe term in general.

So as INVALID, while straight to the point, it does have multiple definitions, I'd suggest NOTVALID. That way there is a clear distinction between Valid and NOTVALID.
