Good catch... teach me not to go back to the standard...
I suggest now using:

  typedef struct ldap_attributetype {
	 char *at_oid;		/* REQUIRED */
         char **at_names;	/* OPTIONAL */
         char *at_desc;		/* OPTIONAL */
         char *at sup_oid;	/* OPTIONAL */
         char *at_equality_oid;	/* OPTIONAL */
         char *at_ordering_oid;	/* OPTIONAL */
         char *at_substr_oid;	/* OPTIONAL */
         char *at_syntax_oid;	/* OPTIONAL */
         int  *at_single-value; /* 0=no, 1=yes */
  } LDAP_ATTRIBUTE_TYPE;

Yes... life with OIDs!  I suggest writing the parser per the spec.
Then, for now, when slapd builds it's internal structure, it can require
a name.  We'll lift this restriction once we have OID support in place.

It to separate parsing/generation from use.  Parsing/Generation of schema
specification in standard formats is something generally useful to both
LDAP clients and servers.  However, each client/server will likely use
the schema information in different ways.  If there is enough commonality
between uses, some additional utilities could be made sharable.
