Pascal case attribute name

[MihaMarkic]

Shouldn't be something like NewtypeAttribute as per conventions?

Literally semi-agree, I like my keyword-likes and namespaces lowercase; but it does look awkward with the [brackets] and the <type>.

Good feedback, I had that nagging in the back of my head... It's 2:1 in favour of PascalCase now.
