Nice work! Thank you for implementing the idea of deep linking the corresponding standard for each test (see #1055) :)

But you realize that's not what I've done? I couldn't deep link to the standard because I wouldn't know which version of the standard to link to. Therefore I linked to the testing notes (which should apply to all (recent) versions)

Oops, I missed that. But you are right. As the same test can be in different versions of the standard and sometimes required or recommended, the link to the testing notes seems to be a good tradeoff. This way one can also get quickly to the standard itself using the navigation.
