Hi Holger,
That was a really good tip. I think this should work for me. I tried it out
and it so far appears to have the potential. The use element along with
correspondingElement is what I'm planning to use.
I had tried the second approach you mentioned of loading the SVG using
getURL(). The problem with that approach for me was the CSS properties are
shared by the main document. So, if I have style with the same name such as
.st3 - that goes global i.e. if the included SVG has a style called .st3
and the parent SVG also has a .st3 style then the new style for st3 appears
across the composite document even if the included SVG is within an SVG
block - it looks like style information is global and not scoped to the
enclosing SVG.
The use element retains this scoping and hence works well.
Thanks,
Shreesh

Hi Shreesh
are you embeding your SVG inside another SVG ? if yes, you are probably
looking for
<use xlink:href="another.svg#someshape"/> which will give you access to
the "shadow" DOM.
sadly this is only implemented in ASV6 and Batik.
a workaround im using is to use getURL() to load the image, and then
append it to the current document, in this way the images DOM will get
part of the documents DOM.
