Description
Artifact-capability of an IdP can be determined from IdP metadata. (If there is no ArtifactResolutionService with a binding that the SP supports, then a request with an ACS URL that expects artifacts will definitely fail.)
A SessionInitiator could fail before redirecting, thus it could allow several SessionInitiators chained together with different defaultACSIndex values. (Similarly to the case of a SAML2 SessionInitiator and SAML1-only IdP.)
