Hello Dave,

XEP does not support flow maps (neither multiple flows) at the moment.
See http://www.renderx.com/reference#XSL11_Support.

We used to have it implemented in another formatting engine. However,
when it came to producing some good looking samples, the "flow maps"
feature appeared to be less valuable than I expected.

Myself I felt very enthusiastic about this feature and the
implementation, and I've produced a few issues of a newspaper - several
regions, several flows, different design for first, last, left and right
pages, headers and footers and so on. It looked pretty good. But as any
newspaper, it had a fixed number of pages.

At that time I understood that the "flow maps" feature does not give
much help to produce good looking newspapers with *arbitrary content*,
because arbitrary lengths of concurrent flows result in a lot of blank
space, long "tails" or dropped content (in case of fixed number of
pages). Creating an newspaper issue still requires the same *manual
editing* of content to make it fit the regions.

If we could have a way do declare how empty instances of regions (their
own flow-source-list already drawn) could get joined or reassigned to be
used by those flows that still have some content to draw -- that would
probably make more sense.

Well, that was a short and not well spoken explanation of why we do not
have this feature implemented in XEP. If you have real-world examples
where this feature is used - I'd appreciate some links.
