An implementation can a) generate values of a syntax and/or
parse values of a syntax.  A syntax which does only a) or
does only b) can be said to partially support a syntax.

We only publish LDAP syntaxes for which we are capable
of parsing (regardless of whether we are capable of
generating values of the syntax).

There are a number of syntaxes which our server is capable
of generating values of, but not capable of parsing values
of.

I've been working on just that with LDAPbis... see
