Actually, I'm surprised the process got as far is it did. The tgroup element in your
table lacks a required cols attribute. In the stock template matching on tgroup in
fo/table.xsl, it checks for the absence of that attribute and terminates processing
with this message:
Error: CALS tables must specify the number of columns.
So I'm surprised you even got a well-formed FO file to feed to FOP. Try adding the
cols attribute and see if that works.
