Re: CP remove hgroup add an outlineMask attribute.

The CP mentions the possibility of 'misuse'. And an @outlinemask 
attribute could in theory be added to heading without a directly 
preceding heading element. Is that part of the proposal? Is that a use 
or a misuse? What happens if done?

If yes, then a perfect CSS display value for <h1-h6> elements with the 
@outlinemask  set, would often be the CSS 3 run-in display. For 
instance, I have in front of me a text that looks something like this:

  <h1>1.5 Stress in Russian pronouns of the 3rd person</h1>
  
  <h2 outlinemask >In the nominative case</h2>
  <p>Bla bla description.</p>

  <h2 outlinemask >In the oblique cases</h2~
  <p>Bla bla description.</p>

<h1-h6> elements with the @outlinemask set would thus be able to 
replace cases where the one currently uses <b> or <strong> in order to 
highlight the first sentence of a sentence etc. Of course, it should 
and would not replace every such use of <b> or <strong>, but there are 
many cases where it would, could and - I think - should.

The weakest point of such a solution seems to be that it could create a 
mess with regard to rank. E.g. considering the above example, what if 
you add a <h3> element without the @outlinemask *after* the above 
example? E.g. to the blind reader, he or she will create an 'outline' 
in his head, and as a result perhaps think that the leve 3 header is a 
'child' of the preceding <h2 outline> ? 

This - btw - seems like a problem - in principle - with all the other 
proposals as well, except the <hsub> proposal.
