Properties defined in the <env> section of an X-DDL document have the lowest priority of all configuration sources and can be easily overridden using system properties and environment vars. Properties values defined in the <env> section may reference other system properties and environment vars, but use ${} variables, but variable values are only resolved from the property source passed in, not other properties defined in the <env> section. If a value defined in an <env> section was already defined in the property source passed in to VMConfigurer, that <env> value is replaced (overridden by) the value passsed in.
