Hi Ron,
I'm not able to duplicate this problem. I'm using your files with Oxygen
10.3, DocBook XSL 1.75.1, Saxon 6 and XEP 4.13, Java 1.6.0_05.
Two things:
1. I didn't see where you described the directory structure containing your
files. As far as I can tell, they all reside in the the current directory,
except the graphic which is in a subdirectory named 'images'. Is that
correct? I wasn't clear what you expected the src attribute in the fo file
to be, as compared to what you got.
2. Normally the XInclude processor does not add xml:base unless an included
file is in a different directory, and that doesn't seem to be the case here.
I'm wondering where the full path information came from, because it does not
appear to be in the XML files. Normally a processor will work with relative
paths, but the error message indicates a full path. Is a catalog involved
here?

Subject: [docbook-apps] xml:base problem with nested XIncludes
Hi
A problem with nested XIncludes that I raised in 2005 has either not
been resolved, or has risen again in DB5 and 1.75.1. The problem is in
the value of xml:base which results in the generation of bad paths to
files referenced in a nested XInclude. A sample program to demonstrate
the problem is below, and the separate files are attached. XEP reports
the bad paths - see below - but fop just fails to produce any diagnostic
output. A work around is to pre-process the XIncludes and appropriate
xsl code is in the file copy.xsl
root0.xml XIncludes root1.xml which XIncludes file0.xml which references
a jpg file in a <figure>. The file cannot be found because the xml:base
is wrongly applied.
Tool chain Oxygen 10.3, DB5, XSL 1.75.1, Saxon-6.5.5 and
XEP-4.10-20070727.

If the nested Xincludes are expanded first using the following XSL, then
the nested problem is avoided and all is well, the image file is found
