question on SVG Tiny 1.2 DOM

Dear all,

I am looking at the http://www.w3.org/TR/SVG12/svgudom.html
(version of March 18)
--------------
A.2.3 ...
The type of elements which can be created through the createElementNS 
method is restricted to:

   1. The SVG namespace.
   2. The following elements: <rect>, <circle>, <ellipse>, <line>,
      <polyline>, <polygon>, <path>, <text>, <image> <anchor> and <use>

--------------
I wonder about a few things:
1. the easy one: <anchor> should really be <a> right ?
2. the difficult ones: why is <g> not in this list ? whereas I can 
understand why <set> is not in, why are the <animate*> not in ?
3. the wild ones: would <audio> and <video> be allowed in this list ?

Thanks
Best regards
JC Dufourd
