+numbers and ordinals.  This package provides the following date and time
+styles: @code{en-fulltext}, @code{en-FullText}, @code{en-FULLTEXT}, and the
+additional time style @code{en-Fulltext}. (The date equivalent can be obtained
+through commands like @code{\\Today}.)
+
+Unlike the base styles provided by @file{datetime2.sty}, these styles aren't
+expandable styles.  This means that you can't use the date or time in PDF
+bookmarks or in the argument of certain commands, such as
+@code{\\MakeUppercase}, while these styles are in use.")
