if the value evaluates to null, the variable will be REMOVED.

How can i check whether it is really removed (except using scriplets)...

This could be done in the following way



empty will check on null, or "" , empty array or collection, etc.

but this doesn't distinguish between whether an(object exists and is empty) and object doesn't exists....

simply print it using EL
If attribute name is removed, value will not get displayed.
 
It is sorta covered in the JavaRanch Style Guide.
