Different output when using fop with -xsl and -xml and when doing two
steps (xalan/fop)
When I use xalan to produce .fo file and then process it with fop I get correct result.
Not so when running fop directly.
I was expecting both approaches to produce identical results since it is my understanding
that fop is using xalan internally. Any idea why it is not? Or can someone confirm it as a bug?
I'm using fop 0.20.5 with xalan 2.5.2.
I'm running them as follows in the same batch. Content of the example
test files (export.bat, test.xslt, test.xml) is below.

The problem is the disable-output-escaping="yes". This affects
how an output file is generated but has no effect if the result
tree of an XSL transformation is fed directly into the FO processor.

This is not a bug.

You should not use this kind of construct, ever. Well, at least unless
you clearly know what you are doing. Please refer to your favorite XSLT
tutorial and/or book for how to write XSLT properly.
