A parser not only processes namespace declarations, verifying their correctness, but it also ensures that an XML document is namespace well-formed.

解析器不仅要处理名称空间的声明、验证它们的正确性，而且还要确保XML文档是名称空间格式良好的。

MXML files are, at heart, well-formed XML files, which means the XML namespaces serve the same purpose as any XML namespace does, that of keeping different tag names lexically scoped.

MXML文件本身就是一种合乎规格的XML文件，所以里面的XML命名空间跟一般的XML命名空间并无不同，即限定不同的标记名称的语法作用域。

A message in the document binding style must simply be made up of well-formed, namespace-qualified XML.
