XML namespaces and attributes

Question

I\'m trying to understand how namespaces work in XML. When I have an element like foo:bar, the attributes will often not have namespaces on them. But sometimes they will. Ar

Answer 1

Examples to illustrate using the Clark notation, where the namespace prefix is replaced with the namespace URL in curly brackets:

is

<{}bar
    {http://www.foo.com/}baz="baz"
    {}qux="qux"/>
<{http://www.foo.com/}bar
    {http://www.foo.com/}baz="baz"
    {}qux="qux"/>
<{http://www.foo.com/}bar
    {http://www.foo.com/}baz="baz"
    {}qux="qux"/>
