Dear all,

The last Hypertext Coordination Group teleconference focused on Media 
Fragments. You can read the minutes at 
http://www.w3.org/2011/07/01-hcg-minutes.html

We discuss the fact that both SVG and CSS talks about the use of the 
fragment identifier in a URI:
   - CSS 3: http://dev.w3.org/csswg/css3-images/#url
   - SVG 1.1: http://www.w3.org/TR/SVG/struct.html#Overview and 
http://www.w3.org/TR/SVG/linking.html#SVGFragmentIdentifiers

And we discuss in particular:
  * Boris's concerns about backwards compatibility of media fragments 
with SVG, 
http://lists.w3.org/Archives/Public/public-media-fragment/2011May/0014.html
   * Fantasai's concerns about spatial media fragments on an image file 
that might have multiple images of different sizes or no clearly defined 
size, 
http://lists.w3.org/Archives/Public/public-media-fragment/2011May/0021.html

During this discussion, people confirm our intuition that SVGview having 
a XPointer like syntax while the Media Fragment URI will always have an 
equal sign tend to show we will not have a syntax clash. Furthermore, 
CSS co-chair agrees that that the problem of multiple images of 
different sizes or no clearly defined size (and #xywh dimension) should 
be stated as a border case and undefined for media fragments (or let to 
be defined for MF 2.0 or something).

Doug (for SVG) plans to send some details comments on our lists.
The CSS WG will discuss the Media Fragments spec during their telecon 
this Wed and will report afterwards on their definitive conclusion.
We will wait for this final feedback before transitioning to CR.
Best regards.

   RaphaŽl
