Sync Permission at Object / Document Level
Please allow Read & Write Sync Permissions to be per object (aka: Document) being processed, rather than at partition-level. Thereby allowing to use '%%root' as a Function's parameter to access the Document to allow permission for read or write per request. Also the permission would carry (deep) through for nested / embedded objects & List<>s. Further, please expose (if not available via '%%root') the Schema (at minimum the "title" property to access Object type).
