         | 
         | It's not _often_ that you want to represent something as a
         | "bold" style without representing it as having strong emphasis,
         | but there are times. A header is a good example of a place
         | where you might want the header to be styled bold, but strongly
         | emphasize a single word in the header. Since <header> doesn't
         | apply the styles that - say - h1 does, it would be perfectly
         | reasonable to script your header as
         | 
         | ``` <header><b>The <strong>Worst</strong> Case

         |

         | Obviously there are a few other edge cases but I will admit
         | that the vast majority of the times would naturally call for a
         | strong tag, over a bold tag. And for those majority cases, I'm
         | really glad that it's "strong" rather than bold, because
         | "strong" is meaningful in different ways than "bold" and it
         | always makes more sense, to me, reading it back as html telling
