Saxon

I experience the following problem with the attached stylesheet that uses "cast as" in an attribute value template:

$ java -jar saxon9he.jar -xsl:castAsInAVT.xsl -s:castAsInAVT.xsl

java.lang.NullPointerException

I have the same problem with Saxon-PE and Saxon-EE from inside oXygen. I updated version 9.3.0.5 that came bundled with oXygen to versions 9.3.0.11 and 9.4.0.3 by replacing saxon9ee.jar in oXygen's lib directory, but the problem remains.

This looks a lot like Bug #651, but as that issue is seven years old and closed, I'm opening a new one.
