Those things are already well documented.  KEYWORD per se is documented in description
of -s and -k options in rcorder(8)
And usage of KEYWORDs shutdown and nostart in rc process is documented in rc(8)

Well, it is up to you to decide.

Problem is that behaviour of PROVIDES, REQUIRES and BEFORE words 
and relationship between files and conditions are almost not documented.
It is not even obvious from manpage that files and conditions lie in separate namespaces.
