This list represents items needed to be done which are architectural in nature, or have to do with the IdAS API/SPI interfaces.

  • Support for "building block" context providers (e.g. that do certain kinds of attribute transformation). 171294
    • Each building block context will expect to be told the rest of the chain of contextRefs.
    • Perhaps a Factory takes a list of ContextRefs instead of a sole ContextRefs
    • When the consumer of IdAS finally gets the Context instance, that instance might be the head of a chain of Context instances. Perhaps the registry only sees the top one.
