2.2: a conformant binding capability must let extra metadata be bound without disturbing existing bindings (for example adding an alternative confidentiality label), make alterations to data objects and their metadata detectable, allow metadata to be bound at whatever stage of its life the information has reached, bind metadata to individual elements of composite data objects (to support redaction and sanitisation before access or release), and cope with current and emerging protocols and formats of data and metadata. The mechanism binds any type of metadata to finite data objects and does not require existing protocols or formats to change (1.3 to 1.5).
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
