 ==== Class conditions
 The `@ConditionalOnClass` and `@ConditionalOnMissingClass` annotations allows
-configuration to be included based on the presence or absence of specific classes.
-If you are using the `@ConditionalOnClass` annotation directly on the class you are conditionally
-registering, you can actually use the `value` attribute to refer to the real class,
-even though that class might not actually appear on the running application classpath.
-This is due to the fact that annotation metadata directly on a class is parsed
-using http://asm.ow2.org/[ASM]. You can also use the `name` attribute if you prefer to
-specify the class name using a `String` value, which is required if you are using
-`@ConditionalOnClass` or `@ConditionalOnMissingClass` as apart of a meta-annotation to
-compose your own composed annotations or in an `@Bean` method as neither of these cases
-are handled by ASM.
