Sure, the SVG WG is looking into creating a normative document that can 
be referenced.  Until we produce that document, it seems reasonable to 
me to have such a chart in the HTML5 draft.

It is notable, however, that in his most recent email on the subject 
[1], Ian seemed disinclined to remove the whitelisted elements in any 
future draft of the HTML5 spec, despite feedback from implementers that 
having a normative list elsewhere seemed acceptable [2][3].

In fact, it's disheartening that seems to have made no substantive 
changes to the original proposal based on the feedback by the SVG WG.

In particular, I was personally disappointed that the request to call 
out unquoted attributes and case-folding as parse errors was not 
incorporated; with all due respect to the people he cites in opposition 
to the idea, this seems to have been made with no proof of technical 
problems, implementation cost, or performance issues, and it raises 
considerable risk to SVG as a format in existing User Agents, including 
authoring tools.  I request that at least some real data be collected 
and exhibited to support his position.
