[docbook] Xinclude processing with docbook 5

[Johnson, Eric]

What xinclude processing tools are people using with docbook 5?
I'm using the latest xerces with saxon and as soon as I switched from
using the namespace unaware stylesheets to the namespace aware
stylesheets my xpointer references stopped resolving.
Using oXygen 9.2, the xpointers resolve nicely but I need something that
can run outside the editor for batch processing.
