default declaration

基本解释

Remove the redundant default namespace declaration on the b start tag.
删除 b 起始标签中多余的默认名称空间声明。
The default namespace declaration, if any, then all other namespace declarations, in alphabetical order of the prefixes they define.
如果有默认名称空间声明的话紧跟在后面，然后是其他名称空间声明，按照定义前缀的字母顺序。
If the back end system that consumes this generated XML is not capable of handling such elements, the serializer can be configured to generate a default namespace declaration.
如果消费这些生成的 XML 的后台系统不不能够处理这样的元素，可以配置序列化器生成一个默认的命名空间声明。

They are protected by the full faith and credit of the United States and preventing default is no less justified than using American military power to protect against an armed invasion without a congressional declaration of war.
