fo:sequence-specification question

Hello,

I am a bit confused about the April draft spec's definition of
fo:sequence-specification (which I abbreviate in this message to 'fo:s-s')
According to the spec, a single fo:s-s can contain any number and
combination of fo:s-s-singles, fo:s-s-repeatings, and fo:s-s-afternatings,
in any order.  But how does this work?  For example, how can I have an
fo:s-s with an fo:s-s-repeating followed by an fo:s-s-alternating?  My
understanding is that at this point we don't have a way to explicitly
associate different fo:flows with different fo:simple-page-masters - so
wouldn't the fo:flow defined in the fo:page-layout containing the fo:s-s
simply flow entirely into the repeating sequence (because it's the first in
my fo:s-s)?  Will the 'dangling' alternating sequence just be ignored?

If my understanding is correct, it would seem multiple fo:s-s-singles could
be used in the same fo:s-s (since they just represent a single page), but
only at the beginning of the sequence (otherwise, they'd dangle and be
ignored).

So is it fair to make the following rules for an fo:s-s?

1.	You can have as many s-s-singles as you want, but they must be
grouped together at the beginning of the sequence.
2.	You can only have one of either s-s-alternating or s-s-repeating,
and it must be the last in the sequence.

Thanks for any insight anyone can provide.
