What's wrong with this JSF EL statement?

Question

Code

<c:if test="#{attr1 && !attr2 && (empty attr3)}">

Error returned

The entity name must immediately follow the '&' in the entity reference.

I simply need to check if attribute 1 is true, attribute 2 is false and attribute 3 is not set. Tried without parentheses on first chance, same result.

Thank you

It expects entity name, like &. You can use & & or replace it with and for better readability.
