 * </p>
 * 
 * <h2>uploadMaxFileSize</h2>
 * 
 * Sets the maximum allowable size for uploaded files.
 * <p>
 * If the user attempts to upload a file which is larger than this, then the data <i>is</i>
 * transmitted from the browser to the server (this cannot be prevented with standard HTML
 * functionality). However the file will not be saved in memory or on disk. An error message
 * will be added to the standard JSF error messages, and the page re-rendered (as for a
 * validation failure).
 * </p>
 * <p>
 * The default value is 100 Megabytes.
 * </p>
 * 
 * <h2>uploadThresholdSize</h2>
 * 
 * Sets the size threshold beyond which files are written directly to disk. Files which are
 * smaller than this are simply held in memory. The default is 1 Megabyte.
 * 
 * <h2>uploadRepositoryPath</h2>
 * 
 * Sets the directory in which temporary files (ie caches for those uploaded files that
 * are larger than uploadThresholdSize) are to be stored.
 * 
 * <h2>uploadMaxSize</h2>
 * 
 * Sets the maximum allowable size for the current request. If not set, its value is the 
 * value set on uploadMaxFileSize param. 
 * 
 * <h2>cacheFileSizeErrors</h2>
 * 
 * Catch and swallow FileSizeLimitExceededExceptions in order to return as
 * many usable items as possible.
