Thanks for passing this on. The current WD says very little about the 
display of a spatial Media Fragment. I quote:

"For a spatial URI fragment, it is recommended to emphasize the spatial 
region during playback. For instance, 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."

Therefore, the highlighting is *just* an example. We can decide to stay 
very fuzzy on this or on the contrary recommend some display. My 
personal preference would be to make this bounding box accessible for a 
CSS that could decide what kind of visual effect it wants to apply on 
this region. We can discuss this during tomorrow's telecon.
Best regards.

   RaphaŽl
