<p>
The ARN of a user, group, or role whose policies contain the context keys that you want listed. If you specify a
user, the list includes context keys that are found in all policies that are attached to the user. The list also
includes all groups that the user is a member of. If you pick a group or a role, then it includes only those
context keys that are found in policies attached to that entity. Note that all parameters are shown in unencoded
form here for clarity, but must be URL encoded to be included as a part of a real HTML request.
