+- `conf` node tree that will be copied to the current input of the pipe, each property's
+names and value will be written to the input resource. Input resource will be outputed.
+Note that properties that will be evaluated (in an expression) as `null` for a given input resource will be
+removed from it. E.g. `./conf/some/node@prop=${null}` will add `./conf/some/node` structure
+if not in current input resource, but remove its `prop` property if any).
