Yes, it's a similar idea. XPointer seems focused on XML/XHTML, I'm not sure
what it would take to extend the spec to include HTML. In addition, I don't
really see the point of adding yet another element addressing scheme to the
web. XPath and CSS selectors are already there and familiar to developers.

I agree with Adam here. I don't see that this opens any significant attack
vector. That said, if someone can think of a serious security concern, I'm
all ears.
