   alexmog: we are not proposing to flow content from external resources
            at the moment
   alexmog: providing flow from external resources could be out of scope,
            or the Regions spec shouldn't restrict the origin of a resource
   ChrisL: I don't think it should be out of scope since the alternative
           would be to write script to pull in content
   alexmog: out of scope may be the wrong term
   alexmog: can regions assume that every element or node comes from
            the same origin?
   alexmog: I think it's useful to assume it but it is limiting
   * Bert thinks flowing <iframe seamless data="foo.html"> into a chain
          of regions would be cool...
   dbaron: given the seamless iframes feature of HTLM5, I'm not sure
           how much this matters
   dbaron: if you assume you have seamless iframes then you don't need
           features in CSS
   <ChrisL> is there a benefit to assuming that all the nodes are in
            the same document?
   * Bert put suspects that <iframe> will be a rectangle, like other
          replaced elements.
   <ChrisL> alex: yes, you can determine element order
   alexmog: but we want to allow indirection into a different document
            without changing the style of this document
   alexmog: seamless iframes does not have that option
   alexmog: I have a options on the wiki but I am not yet ready to
            commit to any of them
   <dbaron> TabAtkins: there are security concerns with integrating
            iframes and, e.g., determining the height of the contents,
            without using the mechanisms in seamless iframes
   alexmog: one option involves using an iframe element; another uses
            a separate property; a third uses a flow rule. we can
            discuss these but work remains to evaluate the solutions
            as well as understand seamless iframes
   tabatkins: this should be discussed on www-style as there are issues
              with it
   alexmog: the Regions spec should note that the content of a named
            flow may come from another document
   vincent: should we retitle the bug?
   vincent: we can note in the spec that the current version assumes
            the content comes from the same document pointing to an
            issue to resolve it later
   Bert: this is not really a Regions issue but a general question of
         whether we can have replaced elements that are reflowing
   vincent: how do we deal with this issue?
   bert: put it on the agenda
   ACTION: alexmog to rework 15811 as a general issue of replaced content
                      and flow

Options for a mechanism were added to the wiki, but we've decided to defer this feature to level 4. I've added a link to the level 4 wiki page


and added a note to the current draft that this is a future feature:
