A friend of mine had to use this and I thought it was something worth remembering for the Springframework.
<util:list id="tmDateFormats" > <value>yyyy-MM-dd</value> <value>dd-MMM-yy</value> <value>MM/dd/yyyy</value> </util:list>
He injected them with SpEl
@Resource(name="tmDateFormats") private List<String> dateFormats;
