Quoting Peter Moulder <Peter.Moulder@...38...>:
Support for this format would be much better if it maximized its use
of
SVG such that the many existing SVG applications could at least render
it. E.g. the above would become
<svg:rect
class="gr1 P1" draw:layer="layout"
width="7.62cm" height="5.715cm" x="8.89cm"
y="9.525cm" />
In principle this approach would be much better; the one caveat is that the SVG
specification flatly forbids placing any SVG elements (except for <svg>) under
a non-SVG-namespaced parent, so it would need to be SVG all the way up to an
SVG root element embedded somewhere in the document.
(Actually, as you may recall, supporting such SVG islands natively is a
long-term goal for Inkscape)
