Patching saxon did the trick.

The index code in DocBook XSL is complex, to say the
least.  Every time I try to work with it I have to review
my five pages of notes so I understand what the complex
expressions are doing. In this case, since there is no
indication of the line number causing the problem, finding
the cause of this error would not be easy.

I did notice, however, that the saxon bug report includes
a patch for Saxon.  You might try that.
