Comment:

Hello SYMM Working Group,

just a few post-deadline questions, I'd like to ask:


1) If several external, internal timesheets are provided and
the document contains for example some SMIL animation inside
(like SVG) - how are the priorities? Similar to CSS priority
rules/specifities? Priority by timing or in case of collisions
the order in the source code of the host document?

2) I think, for details about the interaction with CSS for
example something like the SMIL animation sandwich model
is applicable as usual?

3) What about adopting animateTransform from SVG?
Because many 'designers' seem to like to rotate, to distort
content for decorative purposes, this might be a useful
feature especially for timesheets to cover more of the
stuff people might be interested in.
I think, there were already some efforts from
apple to integrate such feature into CSS, could be
better covered by SMIL/SYMM of course...

4) Why no path-animation for animateMotion
(SplineAnimation Module)? and could be useful to
adopt keyPoints from SVG ...
With only values-animation there are no really
smooth paths available and some 'designer'
might prefer the soft trajectories more than
the hard edges of values-animations.

5) Because animate anyway animates any property or attribute,
is animateColor really required for timesheets - if yes, why?

6) Now something like
'<link href="timesheet.smil" rel="timesheet" type="application/smil+xml">'
is allowed in the current draft for non-XML. This is pretty nice.
Why not to add something like this for XML:
<?xml-stylesheet href="timesheet.smil" type="application/smil+xml"
title="timed styling" alternate="yes" ?>

In both cases it is already defined by the type attribute, what the
user-agent has to expect, therefore I cannot see a specific problem
with this variant for XML and it avoids confusing messages from validators
without the ability to validate multiple namespaces in one document.
