+/**
+ * A sequence of validation groups.
+ *
+ * When validating a group sequence, each group will only be validated if all
+ * of the previous groups in the sequence succeeded. For example:
+ *
+ * $validator->validate($address, null, new GroupSequence(array('Basic', 'Strict')));
+ *
+ * In the first step, all constraints that belong to the group "Basic" will be
+ * validated. If none of the constraints fail, the validator will then validate
+ * the constraints in group "Strict". This is useful, for example, if "Strict"
+ * contains expensive checks that require a lot of CPU or slow, external
+ * services. You usually don't want to run expensive checks if any of the cheap
+ * checks fail.
+ *
+ * When adding metadata to a class, you can override the "Default" group of
+ * that class with a group sequence:
+ *
+ * /**
+ * * @GroupSequence({"Address", "Strict"})
+ * *\/
+ * class Address
+ * {
+ * // ...
+ * }
+ *
+ * Whenever you validate that object in the "Default" group, the group sequence
+ * will be validated:
+ *
+ * $validator->validate($address);
+ *
+ * If you want to execute the constraints of the "Default" group for a class
+ * with an overridden default group, pass the class name as group name instead:
+ *
+ * $validator->validate($address, null, "Address")
+ *
+ * @Annotation
+ * @Target({"CLASS", "ANNOTATION"})
