Saxon

With byte-code generation enabled, the script that follows will not compile.

Two notes:

i) It runs without byte-code generation.

ii) If either of the xsl:with-param instructions in the xsl:next-iteration instruction is commented out, it compiles. Only when both are present is there an error.
