+Define tagging attribute options or option tag/range prefixes.
+Options must not end with `-', prefixes must end with `-'.
+The `lang-' prefix is predefined.
+If you use the
+.B attributeoptions
+directive, `lang-' will no longer be defined and you must specify it
+explicitly if you want it defined.
+
+An attribute description with a tagging option is a subtype of that
+attribute description without the option.
+Except for that, options defined this way have no special semantics.
+Prefixes defined this way work like the `lang-' options:
+They define a prefix for tagging options starting with the prefix.
+That is, if you define the prefix `x-foo-', you can use the option
+`x-foo-bar'.
+Furthermore, in a search or compare, a prefix or range name (with
+a trailing `-') matches all options starting with that name, as well
+as the option with the range name sans the trailing `-'.
+That is, `x-foo-bar-' matches `x-foo-bar' and `x-foo-bar-baz'.
+
+RFC 2251 reserves options beginning with `x-' for private experiments.
+Other options should be registered with IANA, see RFC 3383 section 3.4.
+OpenLDAP also has the `binary' option built in, but this is a transfer
+option, not a tagging option.

+
+The syntax for time limits is 
+.BR time[.{soft|hard}]=<integer> ,
+where 
+.BR integer
+is the number of seconds slapd will spend answering a search request.
+If no time limit is explicitly requested by the client, the 
+.BR soft
+limit is used; if the requested time limit exceeds the
+.BR hard
+limit, an
+.I \"Administrative limit exceeded\"
+error is returned.
+If the
+.BR hard
+limit is set to 0 or to the keyword 
+.IR soft ,
+the soft limit is used in either case; if it is set to 
+.I -1 
+or to the keyword 
+.IR none , 
+no hard limit is enforced.
+Explicit requests for time limits smaller or equal to the
+.BR hard 
+limit are honored.
+If no flag is set, the value is assigned to the 
+.BR soft 
+limit, and the
+.BR hard
+limit is set to zero, to preserve the original behavior.
+
+The syntax for size limits is
+.BR size[.{soft|hard|unchecked}]=<integer> ,
+where
+.BR integer
+is the maximum number of entries slapd will return answering a search 
+request.
+If no size limit is explicitly requested by the client, the
+.BR soft
+limit is used; if the requested size limit exceeds the
+.BR hard
+limit, an 
+.I \"Administrative limit exceeded\"
+error is returned.
+If the 
+.BR hard
+limit is set to 0 or to the keyword 
+.IR soft , 
+the soft limit is used in either case; if it is set to 
+.I -1 
+or to the keyword
+.IR none , 
+no hard limit is enforced.
+Explicit requests for size limits smaller or equal to the
+.BR hard
+limit are honored.
+The
+.BR unchecked
+flag sets a limit on the number of candidates a search request is allowed
+to examine.
+If the selected candidates exceed the 
+.BR unchecked
+limit, the search will abort with 
+.IR \"Unwilling to perform\" .
+If it is set to
+.I -1 
+or to the keyword 
+.IR none , 
+no limit is applied (the default).
+If it is set to
+.IR disable ,
+the search is not even performed; this can be used to disallow searches
+for a specific set of users.
+If no flag is set, the value is assigned to the
+.BR soft 
+limit, and the
+.BR hard
+limit is set to zero, to preserve the original behavior.
+
+In case of no match, the global limits are used.
+The default values are the same of
+.B sizelimit
+and
+.BR timelimit ;
+no limit is set on 
+.BR unchecked .
+
+If 
+.B pagedResults
+control is requested, the 
+.B hard
+size limit is used by default, because the request of a specific page size
+is considered as an explicit request for a limitation on the number
+of entries to be returned.
+However, the size limit applies to the total count of entries returned within
+the search, and not to a single page.
+Additional size limits may be enforced; the syntax is
+.BR size.pr={<integer>|noEstimate|none} ,
+where
+.B integer
+is the max page size if no explicit limit is set; the keyword
+.I noEstimate
+inhibits the server to return an estimate of the total number
+of entries that will be returned; the keyword
+.I none
+indicates that no limit is applied to the pagedResults control page size.
+The syntax
+.B size.prtotal={<integer>|none|disabled}
+allows to set a limit on the total number of entries that a pagedResults
+control allows to return.
+By default it is set to the 
+.B hard
+limit.
+When set, 
+.B integer
+is the max number of entries that the whole search with pagedResults control
+can return.
+Use 
+.B none
+to allow unlimited number of entries to be returned, i.e. to use 
+pagedResults as a means to allow clients to circumvent size limitations 
+on regular searches; the keyword
+.I disabled
+disables the control, i.e. no paged results can be returned.
+Note that the total number of entries returned when the pagedResults control 
+is requested cannot exceed the 
+.B hard 
+size limit of regular searches unless extended by the
+.B prtotal
+switch.
