Id of the device or devices which we want to edit

Before executing the update, validate the updated device using the schema corresponding to its nodeType (if such a schema exists)

Create the missing ancestors of the paths written by add, copy and move operations, instead of rejecting these operations as RFC 6902 prescribes. Each missing ancestor is created as an empty object, as an add of {} at its path would: a missing array element can thus only be created as the next element at the end of its array, a missing array is created as an object, and a value other than an object or array along the path is still rejected. This allows a user who may only edit a nested property to set it before its ancestors exist.

An ISO 8601 time or a time of the format '<day-name>, <day> <month> <year> <hour>:<minute>:<second> GMT', specifying the latest timestamp any of the affected devices might have received an update in order for the request to be executed. A code 412 error will be returned if at least one device was updated after the specified time
