Hi!
1)
What was the reason to restrict the number of
target-values in the xlink:href-attribute in the
animate element?
CR 2000-nov-02:
19.2.4 "Attributes to identify the target element for
an animation" :
"<uri> must point to exactly one target element which
is capable of being the target of the given animation.
If <uri> points to multiple target elements,[...],
then the document is in error"
I can't find this restriction neither in SMIL1 nor
SMIL2. (and even if so:)

2)
Could this become a canditate for inclusion into SVG2?
Together with the requirement for implementations to
support full Xpointer, loads of redundant code could
be saved.
For example:

<animate xlink:href="xpointer(id('grid')/rect)"
begin="targets.mouseover" [...]/>

would animate all children "rect" of the element with
ID "grid". If the target-elements are to be the
event-listeners as well, it should be possible to just
say "targets". Xpointer in begin- and end- attibutes
would also save a lot writing.

3) I would like to be able to pause an animation, and
the let it resume. I'm not yet proficient, but as far
as I see, currently it's only possible to restart an
animation, or in other words say "play from start",
not "go on".

4)
Also, a short notation to control all ongoing
animations at once would be handy (like "pause" and
"play" in the rightclick-menu of the adobe-viewer)
:
"pause all"; "resume all"; "reset all"; "slomo
forward"; "fast forward"; "slomo backward"; "play
backwards"; "fast backward" ...

5)
http://www.w3.org/TR/smil-animation/
:
"While this document defines a base set of animation
capabilities, it is assumed that host languages may
build upon the support to define additional or more
specialized animation elements. "
