[Vladimir Dzhuvinov]

Link to the example:

‌

[Vladimir Dzhuvinov]

Also, trailing comma in figure 7:

https://openid.bitbucket.io/connect/openid-federation-1_0.html#name-example-openid-provider-ent

‌

      ]
   },
}

‌

[Vladimir Dzhuvinov]

Example JSON in figures 9 and 10 has a starting indentation that is not necessary:

https://openid.bitbucket.io/connect/openid-federation-1_0.html#name-example-signed-jwks-jwt-cla

https://openid.bitbucket.io/connect/openid-federation-1_0.html#figure-10
