Dear Mike, HTML5,

The Media Fragments WG has issued a Last Call WD a couple of month ago 
and would welcome comments from the HTML WG on its entire specification 
"Media Fragments URI 1.0" located at 
http://www.w3.org/TR/2010/WD-media-frags-20100408. If you plan to send 
comments, please let us know and do send your comments to 
<public-media-fragment@w3.org> with "LC Comment" in the subject.

Furthermore, following the coffee discussion Mike and I had 2 weeks ago 
at TPAC, I point you to this bug entered in the HTML5 bug tracker: 
http://www.w3.org/Bugs/Public/show_bug.cgi?id=10723 "support for media 
fragment URIs in relevant HTML5 elements".

This bug describes the particular problem of rendering spatial media 
fragment in a HTML browser. The Media Fragments WG has written this non 
normative paragraph [1]:

"For a spatial URI fragment, we foresee two distinct use cases: 
highlighting the spatial region in-context and cropping to the region. 
In the first case, the spatial region could be indicated by means of a 
bounding box or the background (i.e., all the pixels that are not 
contained within the region) could be blurred or darkened. In the second 
case, the region alone would be presented as a cropped area. How a 
document author specifies which use case is intended is outside the 
scope of this specification, we suggest implementors of the 
specification provide a means for this, for example through attributes 
or stylesheet elements."

We will start discussing with the CSS WG how this styling could be done 
but the Media Fragments WG also thinks that if a default behavior must 
be specified, it should happen in the HTML5 specification.
Best regards.

   Erik & RaphaŽl
