The paths to the properties covered by this mask.
A path is a list of property names separated by dots (.), for example foo.bar means the property bar inside the entity property foo inside the entity associated with this path.
If a property name contains a dot . or a backslash \, then that name must be escaped.
A path must not be empty, and may not reference a value inside an array value.
