Yes, this CSS file can be used. But there's a big BUT: "whole tag" styles will be applied only if there's no styles in objects that override them (i.e. in most cases they will be overridden). You can try to use named styles (but in this case you should insert them into text object manually in HTML mode) and styles by object ID - actually object ID goes to object container DIV in runtime and some styles in object can be inherited (but in this case CSS inheritance may be overridden again).
