+/**
+ * To format dates and/or time according to the current locale use
+ * <code>
+ * <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.
+ *
+ * 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.
+ *
+ * Namespace: System.I18N
+ *
+ * Properties
+ * - <b>Value</b>, date,
+ *   <br>Gets or sets the date to format. The tag content is used as Value
+ *   if the Value property is not specified.
+ * - <b>Pattern</b>, string,
+ *   <br>Gets or sets the formatting pattern. The predefined patterns are
+ *   'fulldate',           'longdate', 'mediumdate', 'shortdate', 'fulltime',
+ * 'longtime', 'mediumtime', and 'shorttime'. Custom patterns can   specified
+ * when the Pattern property does not match the predefined   patterns.
+ * - <b>DefaultText</b>, string,
+ * <br>Gets or sets the default text. If Value is not set, DefaultText will be
+ * shown instead of todays date and time.
