Raphael asked me to forward this request for review from the Media
Fragments WG to this mailing list, since he had problems posting.
(It's probably good that it's not cross-posted to whatwg and
public-html anyway.)

Have a read of http://www.w3.org/TR/2010/WD-media-frags-20100408 and
see if it's sane.

Cheers,
Silvia.

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
