Re: SVG views in values lists

Olaf,
from the SMIL Animation side of the picture escaping can be done with =
percent-encoding.
But that leaves the question of when the SVG renderer will decode the =
percent escapes. The URI definition =
<http://tools.ietf.org/html/rfc3986#section-2.4> suggests that it is =
done after splitting the URL on delims and subdelims, so that would mean =
it would be too late.

In SMIL there may be a workaround using SMIL State, but I don't think =
that's allowed in SVG. And, indeed, in SMIL the href attribute isn't =
animatable (but it may contain SMIL State {attribute value template} =
constructs). But in SMIL you could also break open the values animation =
into a sequence of <set> animations.
