If two or more mutable directives conflict with one another, or if two or more immutable directives conflict with one another, then the directive with the lowest ordinal number takes precedence.

If at least one of the directives in conflict explicitly says of itself that it defers to another directive (or type of directive) or takes precedence over another directive (or type of directive), then such provisions shall supersede the numerical method for determining precedence.

If two or more directives claim to take precedence over one another or to defer to one another, then the numerical method again governs.
