/*-------------------------------------------------------------------
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 draft-ietf-ldapbis-strpro for details (once published).


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.  

IA5String
  Basically same as PrintableString.  There are no examples in X.500,
  but same logic applies.  So we require them to be non-empty as
  well.
