thanks for that quick response.

I looked up the two references, and found that svg will/should be 
prioritized before all others.

And that the UA needs to find out the correct size.

But as stated in the last line it is not clear which one the agent will 
choose if both have the same size.
Which basically means is
	<icon src="small_icon.png"/>
	<icon src="small_icon.gif"/>
the same as
	<icon src="small_icon.gif"/>
	<icon src="small_icon.png"/>
and the UA will choose PNG before GIF or is the xml order forcing th eUA 
to choose png. (which is my thought...)

Thanks, bye.
