+ * Syntaxes - implementation notes:
+ *
+ * Validate function(syntax, value):
+ *   Called before the other functions here to check if the value
+ *   is valid according to the syntax.
+ *
+ * Pretty function(syntax, input value, output prettified...):
+ *   If it exists, maps different notations of the same value to a
+ *   unique representation which can be stored in the directory and
+ *   possibly be passed to the Match/Indexer/Filter() functions.
+ *
+ *   E.g. DN "2.5.4.3 = foo\,bar, o = BAZ" -> "cn=foo\2Cbar,o=BAZ",
+ *   but unlike DN normalization, "BAZ" is not mapped to "baz".
+ */
+
+/*
+ * Matching rules - implementation notes:
+ *
+ * Matching rules match an attribute value (often from the directory)
+ * against an asserted value (e.g. from a filter).
+ *
+ * Invoked with validated and commonly pretty/normalized arguments, thus
+ * a number of matching rules can simply use the octetString functions.
+ *
+ * Normalize function(...input value, output normalized...):
+ *   If it exists, maps matching values to a unique representation
+ *   which is passed to the Match/Indexer/Filter() functions.
+ *
+ *   Different matching rules can normalize values of the same syntax
+ *   differently.  E.g. caseIgnore rules normalize to lowercase,
+ *   caseExact rules do not.
+ *
+ * Match function(*output matchp, ...value, asserted value):
+ *   On success, set *matchp.  0 means match.  For ORDERING/most EQUALITY,
+ *   less/greater than 0 means value less/greater than asserted.  However:
+ *
+ *   In extensible match filters, ORDERING rules match if value<asserted.
+ *
+ *   EQUALITY rules may order values differently than ORDERING rules for
+ *   speed, since EQUALITY ordering is only used for SLAP_AT_SORTED_VAL.
+ *   Some EQUALITY rules do not order values (ITS#6722).
+ *
+ * Indexer function(...attribute values, *output keysp,...):
+ *   Generates index keys for the attribute values.  Backends can store
+ *   them in an index, a {key->entry ID set} mapping, for the attribute.
+ *
+ *   A search can look up the DN/scope and asserted values in the
+ *   indexes, if any, to narrow down the number of entires to check
+ *   against the search criteria.
+ *
+ * Filter function(...asserted value, *output keysp,...):
+ *   Generates index key(s) for the asserted value, to be looked up in
+ *   the index from the Indexer function.  *keysp is an array because
+ *   substring matching rules can generate multiple lookup keys.
+ *
+ * Index keys:
+ *   A key is usually a hash of match type, attribute value and schema
+ *   info, because one index can contain keys for many filtering types.
+ *
+ *   Some indexes instead have EQUALITY keys ordered so that if
+ *   key(val1) < key(val2), then val1 < val2 by the ORDERING rule.
+ *   That way the ORDERING rule can use the EQUALITY index.
+ *
+ * Substring indexing:
+ *   This chops the attribute values up in small chunks and indexes all
+ *   possible chunks of certain sizes.  Substring filtering looks up
+ *   SOME of the asserted value's chunks, and the caller uses the
+ *   intersection of the resulting entry ID sets.
+ *   See the index_substr_* keywords in slapd.conf(5).

+
+3.3.2.  Bit String
+
+   A value of the Bit String syntax is a sequence of binary digits.  The
+   LDAP-specific encoding of a value of this syntax is defined by the
+   following ABNF:
+
+      BitString    = SQUOTE *binary-digit SQUOTE "B"
+
+      binary-digit = "0" / "1"
+
+   The <SQUOTE> rule is defined in [MODELS].
+
+      Example:
+         '0101111101'B
+
+   The LDAP definition for the Bit String syntax is:
+
+      ( 1.3.6.1.4.1.1466.115.121.1.6 DESC 'Bit String' )
+
+   This syntax corresponds to the BIT STRING ASN.1 type from [ASN.1].
+
+   ...
+
+3.3.21.  Name and Optional UID
+
+   A value of the Name and Optional UID syntax is the distinguished name
+   [MODELS] of an entity optionally accompanied by a unique identifier
+   that serves to differentiate the entity from others with an identical
+   distinguished name.
+
+   The LDAP-specific encoding of a value of this syntax is defined by
+   the following ABNF:
+
+       NameAndOptionalUID = distinguishedName [ SHARP BitString ]
+
+   The <BitString> rule is defined in Section 3.3.2.  The
+   <distinguishedName> rule is defined in [LDAPDN].  The <SHARP> rule is
+   defined in [MODELS].
+
+   Note that although the '#' character may occur in the string
+   representation of a distinguished name, no additional escaping of
+   this character is performed when a <distinguishedName> is encoded in
+   a <NameAndOptionalUID>.
+
+      Example:
+         1.3.6.1.4.1.1466.0=#04024869,O=Test,C=GB#'0101'B
+
+   The LDAP definition for the Name and Optional UID syntax is:
+
+      ( 1.3.6.1.4.1.1466.115.121.1.34 DESC 'Name And Optional UID' )
+
+   This syntax corresponds to the NameAndOptionalUID ASN.1 type from
+   [X.520].

+ * 	attributeType = dc 
+ * 	attributeValue = com#'1'B
+ *
+ * in fact "com#'1'B" is a valid IA5 string.
+ *
+ * As a consequence, current slapd code takes the presence of
+ * #<valid BitString> at the end of the string representation

+/*-------------------------------------------------------------------
+LDAP/X.500 string syntax / matching rules have a few oddities.  This
+comment attempts to detail how slapd(8) treats them.
+
+Summary:
+  StringSyntax		X.500	LDAP	Matching/Comments
+  DirectoryString	CHOICE	UTF8	i/e + ignore insignificant spaces
+  PrintableString	subset	subset	i/e + ignore insignificant spaces
+  PrintableString	subset	subset	i/e + ignore insignificant spaces
+  NumericString		subset	subset	ignore all spaces
+  IA5String			ASCII	ASCII	i/e + ignore insignificant spaces
+  TeletexString		T.61	T.61	i/e + ignore insignificant spaces
+
+  TelephoneNumber	subset	subset	i + ignore all spaces and "-"
+
+  See RFC 4518 for details.
+
+
+Directory String -
+  In X.500(93), a directory string can be either a PrintableString,
+  a bmpString, or a UniversalString (e.g., UCS (a subset of Unicode)).
+  In later versions, more CHOICEs were added.  In all cases the string
+  must be non-empty.
+
+  In LDAPv3, a directory string is a UTF-8 encoded UCS string.
+  A directory string cannot be zero length.
+
+  For matching, there are both case ignore and exact rules.  Both
+  also require that "insignificant" spaces be ignored.
+	spaces before the first non-space are ignored;
+	spaces after the last non-space are ignored;
+	spaces after a space are ignored.
+  Note: by these rules (and as clarified in X.520), a string of only
+  spaces is to be treated as if held one space, not empty (which
+  would be a syntax error).
+
+NumericString
+  In ASN.1, numeric string is just a string of digits and spaces
+  and could be empty.  However, in X.500, all attribute values of
+  numeric string carry a non-empty constraint.  For example:
+
+	internationalISDNNumber ATTRIBUTE ::= {
+		WITH SYNTAX InternationalISDNNumber
+		EQUALITY MATCHING RULE numericStringMatch
+		SUBSTRINGS MATCHING RULE numericStringSubstringsMatch
+		ID id-at-internationalISDNNumber }
+	InternationalISDNNumber ::=
+	    NumericString (SIZE(1..ub-international-isdn-number))
+
+  Unforunately, some assertion values are don't carry the same
+  constraint (but its unclear how such an assertion could ever
+  be true). In LDAP, there is one syntax (numericString) not two
+  (numericString with constraint, numericString without constraint).
+  This should be treated as numericString with non-empty constraint.
+  Note that while someone may have no ISDN number, there are no ISDN
+  numbers which are zero length.
+
+  In matching, spaces are ignored.
+
+PrintableString
+  In ASN.1, Printable string is just a string of printable characters
+  and can be empty.  In X.500, semantics much like NumericString (see
+  serialNumber for a like example) excepting uses insignificant space
+  handling instead of ignore all spaces.  They must be non-empty.
+
+IA5String
+  Basically same as PrintableString.  There are no examples in X.500,
+  but same logic applies.  Empty strings are allowed.
