The minutia of parameters between editions

Today I was comparing Oracle Database parameters of a recently upgraded database to the original parameters (this upgrade used export import based upgrade, from 11.1.0.6.0 to 11.2.0.3.0)
In this circumstance we have performed a crossgrade in addition to an upgrade, moving from Enterprise Edition to Standard Edition (yes people do it for a variety of reasons, most related to cost).

Well to cut a long story short, I discovered that audit_syslog_level is an EE parameter that does not appear in an SE database.
