For most types of expressions (and expr: attributes) will do the equivalent of a String.valueOf() on the value, and then escape the resulting string. A notable exception is objects of type GxpClosure where the writeHtml method is called and no escaping is performed. If you are suffering from excess escaping you can either create an implementation of the appropriate GxpClosure interface, or instantiate one of the implementations included as part of the runtime library.
