I am trying to understand why similar FOs intended for various output 
engines generate such different results.



More specifically I have a 6 row 5 column table in which in the last 
row, two cells with data (1^st and last cell) , have 
keep-together.within-page applied.  When I generate a PDF using 
AntennaHouse this row appears on page 2.  But in DocX using xmlmind this 
starts on page 1 and continues onto page two.



I realize we are talking different print engines here.  



Unlike all other XSL-FO processors, XFC is not a print engine. It merely 
translates XSL-FO to word processor formats. Therefore XFC has to cope 
with the specificities and limitations of these word processor formats.



See also "How to adapt your existing XSLT stylesheet to the 
specificities of XMLmind XSL-FO Converter", 
https://www.xmlmind.com/foconverter/adapt_xslt/adapt_xslt.html





But I think that Antenna House is more correct here.



Sure. Antenna House is the reference XSL-FO processor. We, XMLmind, are 
clearly not.







In your userguide you have reference to keep-together and it’s stated 
that “Not supported on block-level objects that contain other 
block-level objects.”  I was curious if this was related here?



Can you let me know if this is a bug, this is the expected output, or 
what we need to do to get a similar output.




This is not a bug but a limitation.


In your docxModifiedFO.xml, you have added keep-together.within-page="1" 
to the fo:block contained in a table cell, which is 100% correct. This 
is translated to paragraph property w:keepLines:


Keep All Lines On One Page

which does not give expected results for your use case.


In my (attached) docxModifiedFO2.xml, I moved 
keep-together.within-page="1" to the enclosing fo:table-row. This is 
translated to row property w:cantSplit:


Table Row Cannot Break Across Pages


which gives expected results for your use case (using latest version of 
XFC of course). See attached docxModifiedFO2.docx.
