And that is a valid concern.  I don't think it will be a really 
pervasive problem. I really don't think we're going to see this as a 
major point of failure when it comes to SVG, HTML5, or both. I do 
understand the concern, though.

But the bug I submitted, and my original email on the topic had to do 
with namespaced entities in the SVG. Not copy and pasting SVG.

I'm assuming we've already worked through the issues related to the 
possibility of mangled SVG in pages today, causing problems when 
accessed by a HTMl5 browser tomorrow. I don't think that the namespaced 
entities will add to this burden. In particular, those embedded by a 
tool like Inkscape are so infused within the SVG that it becomes 
extremely difficult to remove. In fact, trying to remove them manually 
will result in the errors that people are most worried about.

So my response is yes, I understand the concern. But the concern isn't 
specific to the topic in this thread. Unless I'm misunderstanding the 
concern?
