!!! Overview
[{$pagename}] is part of the [LDAP Directory Information Models] and composed of an [attribute Type] (see [RFC 4512] Section 2.5.1) and a set of zero or more attribute options (see [RFC 4512] Section 2.5.2).

[{$pagename}] describes how the [AttributeTypes] are defined within the [DSA] [LDAP Schema]

A [{$pagename}] is represented by the [ABNF]:
%%prettify 
{{{
attributedescription = attributetype options
attributetype = oid
options = *( SEMI option )
option = 1*keychar
}}} /%

where <[attributetype|AttributeTypes]> identifies the [attribute Type] and each <option> identifies an [Attribute Option].  Both <attributetype> and <option> productions are [case-insensitive].  The order in which <option>s appear is irrelevant.

That is, any two <attributedescription>s that consist of the same <[attribute Type]> and same set of <[Attribute Option]>s are equivalent.

! [Examples] of valid attribute descriptions:
%%prettify 
{{{
2.5.4.0
cn;lang-de;lang-en
owner
}}} /%
An [{$pagename}] with an unrecognized attribute type is to be treated as unrecognized.  [Servers|DSA] [SHALL] treat an attribute description with an unrecognized attribute option as unrecognized. [Clients|DUA] [MAY] treat an unrecognized attribute option as a tagging option (see Section [RFC 4512] 2.5.2.1).

All attributes of an entry must have distinct [{$pagename}].
