3.1.5 Message Processing Events and Sequencing Rules

The request messages detailed in section 2 are all unrelated to one another. A client MUST emit request messages according to the events that trigger the requests as described above in the Higher-Layer Triggered Events section. The following sections define the message processing rules separately for the GetProxyTrustConfiguration, LsRequestSecurityToken, RequestSecurityTokenWithToken, and LsRequestSecurityTokenWithCookie message exchanges.
