As you can see, quotas are given in QUOTAS and DEFAULT_USER_QUOTAS structures which are on the same level as the USER elements. In contrast, according to the documentation DEFAULT_USER_QUOTAS should be a child of the USER element and the children of the QUOTAS element should be direct children of the USER element.
