Hi Folks,

Suppose an element is declared to be of type QName:

<element name="example" type="QName" /> 

In an instance document, can the value of <example> be without a namespace prefix:

<example>Hello</example> 

If yes, then what is the namespace URI for Hello?

Suppose I declare a default namespace:

<document xmlns="http://www.example.org">
      <example>Hello</example> 
</document>

Is Hello in the http://www.example.org namespace?
