Re: [docbook-apps] height of rows in tables

[Ron Catterall <ron@catterall.net>]

Thanks again Bob.   It seems clear that XEP is trying to implement 
negative row-heights by subtracting from some value defined 
elsewhere.   Also that XEP is non-conformant in this respect.   So I 
tried Apache fop and got the same results as with XEP from the same 
XML file.

In the meantime, the non-conformance of XEP produces the hard copy I 
was looking for.

I suppose I should try Antenna House next - if that does the same, 
the XML source would be pretty near transportable even if 
non-conformant to the XSL-FO spec.  I really would prefer to  write 
standard source.

Yes, match cells containing <!--  -->
