  Sorry the internal tree model has room to keep lines
only on a 16 bits integer and I can't change that without breaking the
API.
The validation error is right I would guess, except for the line number.

Getting that line number would be hard, even in the streaming case

 xmllint --stream --schema http://www.bibletechnologies.net/osisCore.2.1.1.xsd bible.xml

this was raised upstream and I dropped the request due to the ABI stability
issue. I could try to be inventive and attempt a solution in the case of
streaming, but that's not a simple problem. My first take is WONTFIX as
this is the upstream status-quo, but if you can come with convincing
arguments on reopen of the bug, I may try to spend some time on it :-)
