I'm sorry Mike but I don't see it like that at all. The note about breaking
apart a set of documents means exactly that. If a file is removed and is no
longer related to the set then it is considered individually. If one file
is removed or changed, the set is is not broken apart. I have an 8 month
old at home and I know the difference when she breaks a toy apart, and when
a small piece is removed and changed. You really know it when something is
"broken apart".

To break something apart is not to change one file. It is to "break it
apart"... we went over these definitions together for months, and I thought
we had consensus.

Anyway... certainly an epub document is a "set of web pages" when online.
When offline, these notes do not restrict them in any meaningful way. If
there is lack of understanding on the part of some, I'm guessing we could
issue a note of what our intent was, referencing minutes from the meetings,
but I think it's reasonably clear. I'm also fine if something else from the
epub team is used that works.

Cheers,
David MacDonald
