Re: [docbook-apps] DocBook to FOP transformation produces "fo:table is missing child elements."

["Bob Stayton" <bobs@sagehill.net>]

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.
