作者：littlebat

　　作了一点完善。rss的全部代码已经提交完毕，并且用在了现在的系统中。

　　但是，我发现，至今为止，基本没有什么人用rss来订阅学习日记的的内容。我也不知道为什么？可能最主要的原因是学习日记的内容太少了，太浅了，订阅的价值不大；其次是rss订阅还不为一些朋友了解和习惯使用吧。

　　在使用rome生成的程序中，我发现了rss0.91的一些限制：例如：language是channel的必需元素，copyRight的长度不能超过１００个字符（？），description的长度不能超过？个字符

　　我生成的内容不符合这些限制，所以就不支持rss0.91了（包括RSS 0.91 Netscape 和　RSS 0.91 Userland）。

　　我只是从程序的出错信息中得知这些限制的，还没有具体去学习这些规范。

　　程序类基本完成，页面还没有做。使用rome可以较好的实现所有rss版本和atom的feed。个人认为还是应用得比较成功的。今天早上已经把全部代码和argoUML0.18.1的粗略设计提交到了cvs库。

　　主要类的实现概略：（希望得到你的意见或建议，也供想使用rome的朋友参考。）
