[webkit-dev] Question about detach Render Tree from DOM

[Lucius Fox]

Hi,

I am reading webcore rendering basic,
http://webkit.org/blog/114/webcore-rendering-i-the-basics/

It talks about detaching Render Tree from DOM.
My question is after I detached Render Tree from DOM, is the DOM still
a 'valid' DOM?
meaning, can I still use JavaScript to modify the DOM and webkit won't
crash (since the RenderTree is already detached)?

Thank you.
