    TODO

  - #### order

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Order in which this correlator is to be evaluated. (Related to other correlators.) Smaller numbers go first. Entries with no order go last.

  - #### authority

    Flags: RAM,runtime,AVals:3

    Multiplicity: [0,1]

    TODO

  - #### ref

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Reference to an upstream definition of correlator. It is used as a template for this correlator. TODO refine this specification TODO implement

  - #### name

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Name of the correlator. Should be unique in the given context (object type definition, resource, or system-wide).

  - #### displayName

    Flags: RAM,runtime

    Multiplicity: [0,1]

  - #### description

    Flags: RAM,runtime

    Multiplicity: [0,1]

  - #### documentation

    Flags: RAM,runtime

    Multiplicity: [0,1]

  - #### extension

    Flags: RAM,runtime

    Multiplicity: [0,1]

    Correlators not defined in the static schema. (E.g. dummy correlator used for testing, or custom correlators.)

  - #### none

    Flags: RAM,runtime

    Multiplicity: [0,-1]

    "No-op" correlation that always returns "certainly no owner" result.

  - #### items

    Flags: RAM,runtime

    Multiplicity: [0,-1]

    Correlation using a list of matching items.

  - #### filter

    Flags: RAM,runtime

    Multiplicity: [0,-1]

    Correlation using a query filter.

  - #### expression

    Flags: RAM,runtime

    Multiplicity: [0,-1]

    Correlation using a custom expression.

  - #### idMatch

    Flags: RAM,runtime

    Multiplicity: [0,-1]

    Correlation using ID Match service. See https://spaces.at.internet2.edu/display/cifer/SOR-Registry+Strawman+ID+Match+API.
