Re: [web-annotation] Selecting more than text

The XPathSelector that's in discussion would support this:
https://github.com/w3c/web-annotation/issues/95

Let's say you have /html/body/article with content like:

<p>Here's a paragraph<p>
<img src="..." />
<p>Here's another paragraph</p>

You could select it with an XPath range like so:

start: '//article/node()[2]'
end: '//article/node()[3]'
