xsl:call-template not executed under Saxon-EE
100%
Description
The stylesheet appears to output a <head> element under Saxon-HE (or Saxon-EE with no license), and the element is missing under Saxon-EE.

I have not been able to reproduce this and have requested further information from the user.

Weirdly, the user's hypothesis turns out to be correct: it fails when running with their particular license file, but not with other license files.
Looking more carefully, the license file has an unusual combination of options:
SAT=yes SAQ=yes SAV=no
The -explain output shows that the body of the name="header" template is empty, accounting for the absence of any output when this template is called.

It goes wrong at the point of bytecode generation.
As a consequence of SAT=yes, the option to generate bytecode is set on, but as a consequence of SAV=no, the method to generate bytecode returns null. As a consequence the body of the named template is null, and this results in a call on the template returning an empty sequence.
Two follow-up actions:
(a) issue the user a corrected license!
(b) put a check in the license-creation tool to prevent this happening again (it can happen when licenses are issued manually).

- Fix Committed on Branch 9.8, 9.9 added
In case anything like this should happen again, and just for the sake of code robustness, I have changed Optimizer.makeByteCodeCandidate() to return the supplied expression unchanged (rather than null) in the case where no bytecode generation is performed. Patch applies to Optimizer.makeByteCodeCandidate() in 9.8 and 9.9.
