当我验证我的compound document (compound.xml)时，它会向我提供这些特定的授权错误。我正在使用（http://validator.w3.org/check）
**Namespace prefix gr on grant is not defined** - xsi:schemaLocation="http://tutorialone.com/test/grant/ns grant.xsd">
**Namespace prefix gr on title is not defined** - <gr:title>NIH Clinical Cancer Basic Research Grant</gr:title>
大多数元素都会出现这些错误......我无法弄清楚究竟是什么问题！如果你要验证它，你会得到一个上面前缀错误的列表我是新手，并且不知道相当多的数量。为方便起见，我列出了所有文件！
我尝试在 http：// .... 之前添加 gr：但是这不起作用！我看起来非常仔细，但无法确定问题所在。
