This is the form in which model errors are collected for display and repair purposes. Attrbute "currentRefValue" (which must refer to an existing object) is the key for all instances. Attrbute "newRefValue" (which must refer to an existing object) is the key for all instances. If "updateInfo" contains no chiildren, then the update will be made to all properties in the model having value of "currentRefValue". ID of either an existing object or existing property - same syntax as that found in logs.
