Hi, all-

I'm whole-heartedly behind this notion. Another reason for extending the
pointer-event options that Jim doesn't mention is that when dragging a shape
over a text element, text-selection may capture the focus (I've seen this in
my app and demonstrated it to Chris Lilley and Robin Berjon).

Text is a special case of an SVG primative, in that it is the only one that
requires a child node, that has has unique behavior attached to it
(text-selection), and, arguably, is the only one that natively carries
semantic content apart from its shape. Thus, I don't think it's unreasonable
to extend pointer-events in this way.

If you were to make a more generalized solution, you might also consider
<use> elements and their ilk (referential elements like marker and symbols).
I'm not sure what behaviors one might specify, whether limiting (like
"no-select" for text) or extending (maybe 'pointer-events: reflect-parent'
to group or cascade events, or showing a tooltip like <title> does). Or
