Actual Behavior

When transforming a PDF using XEP, if it uses a theme, the scenario fails with Error: Undeclared namespace prefix {fox}

Possible Solution

Declaring xmlns:fox="http://xmlgraphics.apache.org/fop/extensions" in pdf-generator-0.8.0.jar/com/elovirta/pdf/toc.xsl fixes the problem.

Steps to Reproduce

Run a simple transformation with theme and xep:
dita -v -f pdf2 -i path/to/map.ditamap -o path/to/out/pdf -Dpdf.formatter=xep -Dxep.dir=path/to/xep -Dxep.failOnError=true -Dtheme=../docsrc/samples/themes/dita-ot-docs-theme.yaml

Environment

• DITA-OT version: 4.3.4
• Operating system and version: Windows
• How did you run DITA-OT? dita command and oXygen
• Transformation type: PDF2
