[WAI-ARIA State] More examples and readability

Dear editors,

the list of states and properties [1] in a table format is quite hard to 
read and lacks examples. Thus there is room for ambiguity and 
interpretation.

I would propose, also from a QA and consistency standpoint, to rephrase 
it in a form that is easier to comprehend. For example, see the 
definition of the label element [2] in HTML 4 and compare it with the 
current definition of activedescendent [3].

Enhanced readability would probably lead to a faster adoption of the 
proposed standard. Also reference would be easier if you were not 
required to look up the corresponding ID in the source code.

Best regards,
   Martin
