domain of proprietary vendors that may not have an interest in open solutions.

might be with XSLT and XSL-FO ... these are designed well for what they do
and the meet a set of semantics designed and selected by the working group
that developed the specification.

choice of layout semantics to an open standard's choice of layout
semantics? Certainly the end results of many of the concepts will be
similar since both are producing a paginated output, but how it gets there
is critically important because any expression you may have that follows
the semantics of a proprietary solution would have to be interpreted and
translated to an expression that follows the semantics of XSLT and XSL-FO.
This is not to speak to the architectural chasm between tightly-bound
formatting processors where the transformation task is intimately aware of
the formatting task, and the XSL arm's-length architecture where all of the
transformation has to be completed before any of the formatting can
begin. You will have to find a way to map all of the proprietary semantics
of on-the-fly status checking into XSL's semantics of formatting contingencies.
One important question is: does the proprietary system have a concept of
transformation of XML inputs to an output, or is it similar to a desktop
publishing system of production of a final-form output?
>Does anyone have any ideas or suggestions on this?(1) Manage your expectations ... without even knowing your proprietary
systems, I suspect it will either take magic or human intervention to map
(2) If you can at the least produce a static XSL-FO instance representing
the same output as that of a proprietary solution, then consider how
LiterateXSLT (a free resource available from our web site) might help; it
is an incomplete prototype of XSLT stylesheet inference engine. Using
LiterateXSLT one makes a static snapshot of a completed transformation,
then seeds that snapshot with triggers about transformation based on a
representative XML input. A multi-step process then infers the XSLT
stylesheet required for the XML input to generate the XSL-FO output. That
XSLT stylesheet can then be used with multiple XML inputs. I developed the
prototype long enough to satisfy some UBL work I was doing and then left it
on the shelf for others since I don't have the resources to complete
it. Others have found it useful.
I hope this has helped.
