It also seems to me reasonable suggestion.
However, a reasonable amount (which should be adjusted under discussions)
of description should be self-contained.
For example, "security context is a formatted short string" is not enough
to understand why it is necessary and what is the purpose.
As Robert suggested, a few example and definition of technical terms
will help database folks to understand what it is, even if self-contained
explanation is not comprehensive from viewpoint of security folks.
