Re: ISSUE-2022 (link-activation-behavior): The activation behaviour of <a> elements should be defined [SVG Tiny 1.2]

Hi, Cameron-

Agreed, wording looks good.  Small typo (missing "of" after 
"activation"); here's a correction, along with a suggested addition (if 
you think the added wording helps):

   The activation behavior of the 'a' element is for the
   link to be traversed according to the attributes on the
   element.  Thus, link traversal can be prevented by canceling
   the DOMActivate event that is dispatched by invoking the
   preventDefault() method on the event object.  Note that DOM
   Level 3 Events requires a click event to be synthesized if
   activation of the 'a' element is not performed in response to
   a click event (for example if the user focuses the element
   and then presses the Enter key).  Therefore, a link activation
   must be composed of an optional keydown event, then a click
   event, followed by a cancelable DOMActivate event.


Regards-
-Doug
