Observações

Os parâmetros do token de segurança fornecem informação sobre os tokens (por exemplo, tipo de token, emissor, etc.) exigidos pelo elemento de ligação de segurança.

As classes de parâmetros de token de segurança derivadas deste são um conjunto de propriedades e métodos de token, e são usadas na criação de diferentes tipos de elementos de ligação de segurança e tokens. Nem todas as propriedades são relevantes para todas as classes derivadas. Por exemplo, não ReferenceStyle tem relevância num caso de token emitido (token SAML).
