XML命名空间中的前缀

Question

是否有可能在XML命名空间中使用冒号包含前缀？

像这样的事情

<root xmlns:x:y="...." /> 

Answer 1

结果可能取决于你的XML处理器有所不同。

从NT-Names定义：

The Namespaces in XML Recommendation [XML Names] assigns a meaning to names 
containing colon characters. 
Therefore, authors should not use the colon in XML names except for 
namespace purposes, but XML processors must accept the colon as a name character.
