Before making any changes to the spec text at
http://www.w3.org/TR/media-frags/#media-fragment-display, can we please have
a discussion about the different types of applications that we envisage
using media fragment and thus extract the different "classes" of possible
rendering?

Very interesting idea. IIUC that refers to being able to do some special
styling on the area that is being highlighted in the case where we are not
removing context (similar to how pseudo-classes work on anchors
http://www.w3schools.com/CSS/css_pseudo_classes.asp). It would be
interesting to consider if we can use CSS to remove the areas outside the
"focused" segments and thus achieve the splicing? Something like:
img {
  display: none;
}
img:selected {
  display: block;
}
That would be a means to avoid having to define anything for spatial
fragment URIs - they would only create the regions virtually for any HTML5
technology to work with - e.g. for CSS to style it, for JavaScript to
manipulate it etc.  We could do the same for the time dimension actually,
though the CSS wouldn't work quite that nicely and it would need to be
defined that a CSS change actually has an effect on the displayed controls
for the video (or audio). But it's an idea.

I guess this discussion should actually be had between all the involved
working groups - HTML, CSS and us in particular. I don't think we should be
writing spec text before these discussions have been had, actually.


Cheers,
Silvia.
