There are a number of "default" values and strings used by the display tags to show messages, decide which options to display, etc... This is useful if you want to change the behavior of the tag a little (for example, don't show the header, or only show 1 export option), or if you need to localize some of the default messages and banners.

The defaults can be overriden for just this table via the <display:setProperty name="..." value="..."> tag, or you can override for the entire site via a displaytag.properties file or by directly setting properties at runtime. Look for the "configuration" section in the displaytag documentation for the full list of properties, their default values, and details on how to configure them in your system.
