usually notpresent is used for availability of roles so you can tailor your
pages based on roles. But it basically checks for the existance of objects.
empty is for checking if strings (length of 0) or collections (null) are empty.

The wrapped content of notPresent tag is processed based on whether the object specified does not exist.
notPresent tag can be used with these attributes
cookie, header, parameter , name ,property, role and user
