// have one or more sets of the following information (see the
|
|
// Terminology section for definitions). If more than one set of the
|
|
// following information has been discovered, the precedence rules
|
|
// defined in [XRI_Resolution_2.0] are to be applied.
|

// - OP Endpoint URL
|
|
// - Protocol Version
|
|
// If the end user did not enter an OP Identifier, the following
|
|
// information will also be present:
|
|
// - Claimed Identifier
|
|
// - OP-Local Identifier
|
|
// If the end user entered an OP Identifier, there is no Claimed
|
|
// Identifier. For the purposes of making OpenID Authentication
|
|
// requests, the value
|
|
// "http://specs.openid.net/auth/2.0/identifier_select" MUST be
|
|
// used as both the Claimed Identifier and the OP-Local Identifier
|
|
// when an OP Identifier is entered.
