Can we assign "empty" value using c:set?

Question

I need to assign object value as empty. I know we can use

<c:set var="xyz" value=""/>

But can we assign like below snippet?

<c:set var="xyz" value="${empty}"/>
Its giving me **Unable to parse EL function ${empty}.**

Answer 1

empty is an operator, not a value. You should use ${null}.
