/**
 * To format dates and/or time according to the current locale use

 * <com:TDateFormat Pattern="dd:MMM:yyyy" Value="01/01/2001" />
 *</code>
 * The date will be formatted according to the current locale (or culture)
 * using the format specified by 'Pattern' attribute.
 * The 'Pattern' attribute can also contain two of the predefined presets,
 * the first one for the date part and the second for the time part:
 * 'full', 'long', 'medium', 'short', 'none'.
 * If only one preset is present, it will be used for both the date and the
 * time parts.
 * <code>
 * <com:TDateFormat Pattern="medium long" Value="01/01/2001 15:30:45" />
 * <com:TDateFormat Pattern="full" Value="01/01/2001 15:30:45" />
 *</code>
 *
 * To format date and/or time for a locale (e.g. de_DE) include a Culture
 * attribute, for example:
 * <code>
 * <com:TDateFormat Culture="de_DE" Value="01/01/2001 12:00" />
 * </code>
 * The date will be formatted according to this format.
 *
 * If no Pattern was specified then the date will be formatted with the
 * default format (both date and time). If no value for the date is specified
 * then the current date will be used. E.g.: <code><com:TDateFormat /></code>
 * will result in the current date, formatted with default localized pattern.
