A comment can be added at the end of an MSL expression. The comment ends with the expression's closing parenthesis. Comments are not stored nor retrieved with atom values but are preserved in the MSL text in the hybrid database. Because comments are removed before processing the remainder of the MSL expression, they are not included in hash values.
