I have a (reasonably) simple XML and corresponding Schema file. When I attempt to validate one against the other, netbeans spits out the following error message:
我有一个(合理的)简单的XML和相应的模式文件。当我尝试对其中一个进行验证时，netbeans会输出以下错误消息:
The markup declarations contained or pointed to by the document type declaration must be well-formed. [2]
文档类型声明中包含或指向的标记声明必须格式良好。[2]
This suggests that my Schema file itself is not well formed. However when I validate my Schema file, there is no error. Can anyone spot my mistake (Or otherwise educate me as to what I am not understanding)?
这说明我的模式文件本身并没有很好地形成。但是，当我验证我的模式文件时，没有错误。谁能指出我的错误(或者教育我不理解的东西)?

I am somewhat new to XML. While I am familiar with the general syntax and function, I still find the header section very confusing.
我对XML有点陌生。虽然我熟悉一般的语法和函数，但我仍然觉得标题部分非常混乱。

The doctype element is used for association with DTD, not XSD.
doctype元素用于与DTD的关联，而不是XSD。
use xsi:schemaLocation="maps.xsd" on the root element instead.
使用xsi:schemaLocation = "地图。而是根元素上的xsd。

More precisely, declare xsi namespace and then use it to mark your schema, like this:
更准确地说，声明xsi名称空间，然后使用它来标记您的模式，如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<map xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://example.com/sample" id="testMap" name="Test Map"
xsi:schemaLocation="maps.xsd">
