解决办法1：
在<?xml version="1.0" encoding="UTF-8"?>
下面加上<xml-body></xml-body>，等builder 完毕后再去掉，OK

解决办法2：
将 Preferences > XML > XML Files > Validation中"Honour all XML schema locations"前的对号去掉。它将禁用指向不同schema位置相同命名空间引用的验证，仅以第一次找到的可验证的XML文件为结果。

解决办法3：
点击eclipse左上角菜单栏 Project->clean 清理一下你所出现问题的项目。不仅这个问题，还有很多奇怪的问题都可以通过这种方式解决

解决办法4：
首先为了确保 Eclipse 可以从远程拿到 xsd 文件，到 Window -> Preferences -> General -> Network Connections -> Cache 下的 Cache entries 框内检查所需要的文件是否正确，如果不确定，就点击 "Remove All"，然后右击当前的 Project 选择 Validator，Eclipse 会重新加载 xsd 文件；
