In theory this would be more logical to finish implementing the features
that the spec does describe. However, I can hear the business
motivations behind this proposal. I have nothing against it, I just
won’t try and make a big effort to provide support (either dev or user).

So this is a +0 from me.

A few comments inline.

What about 1,3-5,7,11-? :-P

But PDFBox will still be necessary to insert the external document in
the sequence of pages? Just curious.

Do we really care about that? :-P  “Sorry, it only works with FOP,
you’ll have to use FOP to benefit from this feature.” Isn’t that
a shame.

As long as it doesn’t turn the current architecture upside down. But
I guess it won’t, will it?

Which makes FOP live, anyway.


Have fun ;-)
