/**
* Implementation of the User Attribute Packet (Tag 17)<br/>
* <br/>
* The User Attribute packet is a variation of the User ID packet. It
* is capable of storing more types of data than the User ID packet,
* which is limited to text. Like the User ID packet, a User Attribute
* packet may be certified by the key owner ("self-signed") or any other
* key owner who cares to certify it. Except as noted, a User Attribute
* packet may be used anywhere that a User ID packet may be used.
* <br/>
* While User Attribute packets are not a required part of the OpenPGP
* standard, implementations SHOULD provide at least enough
* compatibility to properly handle a certification signature on the
* User Attribute packet. A simple way to do this is by treating the
* User Attribute packet as a User ID packet with opaque contents, but
* an implementation may use any method desired.
* module packet/user_attribute
* @module packet/user_attribute
