Use 'da' for DICT_ATTR*.  "attribute' is for 'int'
Added %{debug_attr:...} from master

With some simplifications
Use the default request if there's no "." in the reference.

	update outer.reply {
		User-Name := foo
	}

ends up parsing "User-Name" with a default list of "outer",
BUT because "User-Name" has no ".", the old code would return
a hard-coded CURRENT
