Description

We should try to check the checksum in the SEF file, as we do in the Java packageloader, to check that the stylesheet has not been tampered with by someone without an EE license.

(It would not be secure, of course, because the code that checks the checksum can be interfered with, but it's a deterrent.)

If this proves difficult we could use a simpler checksumming algorithm when target="JS".
