After you've clearly stated the relevance of the page
Hmm. Aboutness remains a slippery fellow to pin down IMO.
Maybe I'm putting words into your mouth, but I would suggest that relevance is not a black and white issue, but a spectrum.
I think it is still obviously true that of two otherwise equally connected and trusted pages, one that mentions 'blue widgets' as a heading and repeats it in the text, will outrank (on a search for 'blue widgets') one that only mentions it once in the text.
I don't think it is as easy as we might like to unpick relevance from ranking.
