SEC14 — SecurityFeatures still confusing!

Summary: Okay, I"ll give you there is a need for security features
provided they are only looked at for supported features of
credentials and contexts. Not for setting.
These should be done via setting assoication options and setting the
delegation mode;

To simplfy the semantics of SecurityFeatures and using them,
the spec should specify a good programing model. Otherwise,
examining them and manipulating them becomes ineffcient.
