Saxon

A bit tricky to fix this. The command-line with -nogo option is compiling the stylesheet as if it were to execute, and then simply skips the execution phase; up till then the logic is essentially "compile complete stylesheet" rather than "compile free-standing package". My first instinct was to try and defer the error check (or the reporting of the error) until PreparedStylesheet.newController(); but that method doesn't throw an exception, and if it did, then XsltExecutable.load() would have to throw an exception, which is an unpleasant API change.

I've added a special path to the already tortuous Transform.doTransform() method: if export && !run (i.e. the -export and -nogo options are set) then it uses compilePackage rather than compile, which doesn't require the package to be executable.

Making this change for 10.0 only in the interests of stability.

Bug fix committed in the Saxon 10.1 maintenance release.
