+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'.
+
+RFC2251 reserves options beginning with `x-' for private experiments.
+Other options should be registered with IANA, see RFC3383 section 3.4.
+OpenLDAP also has the `binary' option built in, but this is a transfer
+option, not a tagging option.
