问题
I am trying to track down the following error in my fo file [*]. Since there is no context in the error message I do not understand how I am supposed to search for the root issue.
The fo file has been generated from a proper (at least per XSD validation) docbook 5 file, but the generated fo file is not correct:
$ xmllint --nonet --noout --schema /usr/share/xml/docbook/schema/xsd/5.0/docbook.xsd source/docbook/part02/part02.xml
source/docbook/part02/part02.xml validates
How would one search the root issue (docbook level) from an input 3.2M XML-FO file ?
$ du -sh bla.fo
3.2M bla.fo
[*]
$ fop -d bla.fo bla.pdf

Try validating your DocBook XML using oXygen XML Editor 18.1. According to the oXygen folks, it has improved DocBook table validation: https://lists.oasis-open.org/archives/docbook-apps/201611/msg00044.html
