    14211421  Multiple warnings can be attached to a response (either by the origin server or by 
    1422   a cache), including multiple warnings with the same code number. For example, a server 
    1423   might provide the same warning with texts in both English and Basque.

    14261426  When this occurs, the user agent &SHOULD; inform the user of as many of them as 
    1427   possible, in the order that they appear in the response. If it is not possible to inform 
    1428   the user of all of the warnings, the user agent &SHOULD; follow these heuristics: 
    1429   <list style="symbols"> 
    1430     <t>Warnings that appear early in the response take priority over those appearing later 
    1431       in the response.</t> 
    1432     <t>Warnings in the user's preferred character set take priority over warnings in other 
    1433       character sets but with identical warn-codes and warn-agents.</t>

    1455   The warn-text &SHOULD; be in a natural language and character set that is most likely 
    1456   to be intelligible to the human user receiving the response. This decision can be based on 
    1457   any available knowledge, such as the location of the cache or user, the Accept-Language 
    1458   field in a request, the Content-Language field in a response, etc. The default language is 
    1459   English and the default character set is ISO-8859-1 (<xref target="ISO-8859-1" />).

    1461 <t> 
    1462   If a character set other than ISO-8859-1 is used, it &MUST; be encoded in the
