Note that the link above is to a really old W3C copy of the spec. Here's 
the latest:

   http://www.whatwg.org/html#the-label-element

To answer your question, though: it's actually just used as a way to make 
it non-conforming to put <label> elements (even labels without controls) 
inside <button> elements and <a> elements (and a few other minor cases). 
We don't want to allow those because if you ever do associate a control 
with such a label element, the result is very confusing to the user. (And 
if you've not any intention of ever associating a control with the 
<label>, then it's probably wrong to use the <label> in the first place.)

In particular, note that being in the "interactive" category doesn't 
actually affect how the element interacts. That's defined separately.
