Syntax for referencing a user role in an EL expression when using Page Composer

Content

This EL Expression that I am putting up here will be useful for your page customization.

#{securityContext.userInRole['role1,role2,roleN']}         
When the user has any of the roles, the expression returns True.  When the user does not have any of the roles, the expression returns False.

#{securityContext.userInAllRoles['role1,role2,roleN']}
When the user has all the roles, the expression returns True.  Otherwise, the expression returns False.

#{!securityContext.userInRole['PER_HUMAN_RESOURCE_SPECIALIST_JOB']}
This is a negative condition because of the !. 

#{!securityContext.userInRole['PER_LINE_MANAGER_ABSTRACT'] or securityContext.userInRole['GSE_HR_MGR_LITE']}
