+/**

+ * 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

+ *   'full date', 'long date', 'medium date', 'short date', 'full time',

+ *   'long time', 'medium time', and 'short time'. Custom patterns can

+ *   specified when the Pattern property does not match the predefined

+ *   patterns.
