suggested change for aria poposal

Suggested change  for aria proposal on https://rawgit.com/w3c/coga/master/issue-papers/links-buttons.html  - specifically the section on  Language type support and proposed attributes  of aria-hasAlt and aria-alttype and the different language options such as  easylang numberfree and even summery.

It might be cleaner.  It needs to be as simple as possible to implement and although the easylang in the draft is easier, all the different ways may make it harder to grasp and remember. It might be easier to have one slightly harder way to implement it that works for all our cases (in fact we can make the metadate approach very similar) 




Suggestion replace easylang numberfree litral  aria-hasAlt and aria-alttype  with rel="alternative" and additions to HTML type  :


Option 1: 
<div>
<span rel="alternative"  aria-type="easylang numberfree vocab500"  class="hidden">most people prefer simple text<span>
In studies it was found that only 30% of users prefer long convoluted text with obtuse words and lots of numbers, with 56% claiming there preferred the simplified text , with the remainder unsure or stated it depends on the context </div>


and we can add to html  types as they are mime types (I think)



or  Option 2: (even simpler)
<div>
<span   aria-alternative="easylang"  class="hidden">most people prefer simple text</span>
In studies it was found that only 30% of users prefer long convoluted text with obtuse words and lots of numbers, with 56% claiming there preferred the simplified text , with the remainder unsure or stated it depends on the context 


</div>
 and 
part of this suggestion is we get rid of the following


<span aria-easylang="some text that is easy to read"> some convoluted obtuse text</span>


As an option 3  we could also have the same approach to merge all the  ways to add help such as aria-explain or 
aria-feedback aria-moreinfo and aria-extrahelp  into one attribute aria-moreinfo
 
such as
<button type="button"  >undo


<div aria-more="morehelp" aria-hidden="true"> pressing the undo button will erase all your work on this page. Use this button with care. If you press it by mistake, press control and y at the same time and your answers will come back. </div>


<a href="functiongethelp()" aria-more
="humanhelp" aria-hidden="true">I want a person to help me</a>

</button>




or
<button type="button"  >undo
<a href="functiongethelp()" aria-more
="humanhelp" aria-hidden="true">I want a person to help me</a>
</button>







or (option 4 - can be with option 1,2 and 3)


<button type="button"  >undo
<link aria-more="morehelp" aria-hidden="true" href="myhelpfile.html#undo/> </button>





replacing the following: 
<button type="button" aria-moreinfo="uri2 uri3" >undo</button>






URI 2 may read: 


<div id="uri2" aria-extrahelp="morehelp" aria-hidden="true"> pressing the undo button will erase all your work on this page. Use this button with care. If you press it by mistake, press control and y at the same time and your answers will come back. </div>


<a href="functiongethelp()" aria-extrahelp="humanhelp" aria-hidden="true">I want a person to help me</a>







All the best
