In oracle application framework page we create an OAF Header region to give separate title of the page to give the information of the page functionality to the user.
By using Header region, page content and the header region gets seperated/partitioned for more clear information display.
Header region is also used for some important message display on the Oracle application framework page like Error, Warnig, Information, etc at the top of the page.
By use of Header region, the page level action buttons/links will be displayed both at the top of the page and the bottom of the OAF page.
Note: Header element does not support styleClass attribute.
