[CSS3-GCPM] Three questions regarding footnotes

Hello,

The attached pdf page looks like this:

+---------------------------------+
| Lorem ipsum dolor[6] sit amet,  |
| consectetuer[m] adipiscing[n]   |
| elit. Etiam eros. Donec gravida |
| pede a mauris. Etiam sem eros,  |
| tempus a[7], accumsan pharetra, |
| lacinia aliquam[o], nibh.       |
| Vivamus[p] ac leo. Duis         |
| bibendum dignissim ipsum. Class |
| aptent taciti sociosqu ad       |
| ______                          |
| [m] foo - [n] bar - [o] baz     |
| [p] gaz                         |
| ______                          |
| [6] Blah blah blah blah blah    |
| blah blah blah blah.            |
| Blah blah blah blah blah blah.  |
| [7] Blah blah.                  |

Looking at this page, I have three questions regarding footnotes
(CSS3-GPCM draft):

1) It does not seem possible to have two footnote areas at the bottom
of the page (in the example, one for alphabetic footnotes, one for
numbered footnotes).

2) It does not seem possible to put several footnote references in a
single paragraph (as it is the case, in the example, for the
alphabetic footnote references).

3) The footnote #6 contains two div elements (two paragraphs). But is
it possible to put divs in a footnote? Certainly, something like this
is wrong:
<p>A sentence consists of <em>words. <div
class="footnote"><p>Most</p><p>often.</p></div></em></span>.
Should one close the em tag before the footnote-div and reopen it
afterwards? This would not be clean code.
