A response to a batch request is usually in the form of a 207 (Multi-Status) response. When a status code must be returned for
an entire resource, such as 404 (Not Found), a status element may be added to the response node.
If all operations produce the same successful response, the response body might be omitted, indicating that the HTTP response
code applies to all targets. This convention cannot be used when the response body is used to transmit data, such as in a
successful PROPFIND Method, or when the response body is necessary to show that an error, such as 404 (Not Found), applies to
properties on each resource, rather than to the resources themselves.
