I think we need to be very clear which ASN.1 data type definition
is associated with the OID.  For example

  This LDAP syntax associates the OID 1.3.6.1.4.1.1466.115.121.1.14
  with the ASN.1 data type DeliveryMethod [REFERENCE].  The 
  following "native" string representation is defined for this
  syntax.

An informative copy of the ASN.1 data definition could be
provided as well.

Then the string representation should be defined in terms
of the referenced ASN.1 data type.

I believe each and every LDAP syntax as an associated ASN.1 definition.
In some cases, it might be implicit or defined in some obscure
document.  We need to clarify for each and every syntax what the
ASN.1 definition is.

There may be some syntaxes which are best removed then clarified.
