!!! Overview
The "[{$pagename}]" (audience)  __OPTIONAL__ [Reserved Claim Name] identifies the recipients that the [JSON Web Token] is intended for.  

Each principal intended to process the [JWT] [MUST] identify itself with a value in the audience [JSON Web Token Claim].  

If the principal processing the claim does not identify itself with a value in the "[{$pagename}]" [claim] when this [JSON Web Token Claim] is present, then the [JWT] [MUST] be rejected.  

In the general case, the "aud" value is an array of [case-sensitive] strings, each containing a [StringOrURI] value.  

In the special case when the [JWT] has one audience, the "aud" value [MAY] be a single [case-sensitive] string containing a [StringOrURI] value.  

The interpretation of audience values is generally application specific.
