Re: SVGT 1.2: <image> does not support SVG

Hello www-svg,

A few more points on the svg image vs animation argument.

As already noted, animation is a timed element while svg image (and html
image) are not timed elements.

(And yes, animated GIF should be on the video element, which is timed
and so allows control of the timeline, not on image).

Tiny does not have any clipping. image in 1.1 Full clips the SVG. image
in Full 1.2 could, as noted, reference SVG images, but they should be
static, non-animated images. As Maciej pointed out, if so, this should
define how to generate a static view of an image. CDF is already
defining this for their use of html object, and the same definition
(using snapshotTime) should be used there. SVG images on the image
element in Full 1.2 will also clip, same as 1.1 Full.

The wording:

"If the user agent includes an XHTML or SMIL viewing capability, then a
Conforming SVG Viewer must support resources of MIME type
"image/svg+xml" wherever raster image external resources can be used,
such as in the XHTML 'img' element."

was well intentioned, and was based on experience introducing the PNG
format. Some browsers would allow PNG on img but not on object, not in
the chrome, not as a css background image, etc. However, based on
comments in this thread, we have agreed to remove this requirement.
