Changes

These The following identifiers create links and are designed to accept a single value. Using multiple values or other text will break the link and/or invalidate the identifier. In general, the parameters should include only the variable part of the identifier, e.g. <code>|rfc=822</code> or <code>|pmc=345678</code>.
