I have downloaded spring-modules-validation-0.8a-sources.jar and spring-modules-validation-0.8a- sources.jar. In spring-modules-validation-0.8a-sources.jar there is package name annotation with package orde as org.springmodules.validation-> bean->config->loader->annotation. But in spring-modules-validation-0.8a-sources the package name annotation is missing.I am confused why it is so.As i am trying to write some custom annotaion and i want to take some quick refernce with spring annoation for bean validation with some source files.For eample there are MaxLength,MaxSize and its implementation part in jar files .But it is missing in source files.Thanks
