That could also work, but based on aesthetics I still prefer my first  

     <p class="x-superparagraph">You are here</p>

     .x-superparagraph { font-size: 90% }

     <p class="-superparagraph">You are here</p>

     .-superparagraph { font-size: 90% }

It seems to me that the current spec allows itself to define any  
class name as its own while still allowing authors to use any yet- 
undefined ones. Are you suggesting that the spec disallows the use of  
undefined class names starting with "html-"? What would be the purpose?
