!!! Overview
[{$pagename}] in [LDAP] is a kind of tag that provides additional information about the way that an [attributeType] should be interpreted.  

An [AttributeType] consists of the attribute name or [OID] followed by zero or more attribute options.  

If there are attribute options, then they are separated from the attribute name and from each other using semicolons.  

! [{$pagename}] [Example]
For example, in the attribute description "{{userCertificate;binary}}", the attribute name is "{{userCertificate}}" and the attribute option is "{{binary}}".

[{$pagename}] can be used for several purposes, including providing information about how the server should treat that attribute (e.g., the binary encoding option as described in [RFC 4522])  

[{$pagename}] may also be provided for the benefit of clients in some form (e.g., the language tag options as described in [RFC 3866], which make it possible to provide an attribute value in different languages).
