$AttributeName
In action code contexts other that queries and conditional expressions, an attribute's name prefixed with a $-character implies a reference to that attribute, thus a placeholder for that attribute's value. In a coding context is acts as a variable name where the variable name must be that of an existing attribute and the variable's value is got from or set to that attribute.
In queries and conditional expressions, the syntax implies a shortened Boolean test.
