What's the point of the last sentence?  What else could the client do
with a feature it doesn't know about?

(and [Models] must be added to the References section).

This is missing, adapted from similar texts in [Models]:

  The 'objectIdentifierMatch' matching rule and the
  objectIdentifierFirstComponentMatch (1.3.6.1.4.1.1466.115.121.1.38)
  syntax is defined in [Syntaxes].

I don't think the last sentence is necessary.  I can find no similar
statement about other attribute types in [Models] or [Schema], yet I
assume they can be referred to with other names too.
