// Since dojo/NodeList-html already took the "html" name, this method is called

// module will define an "html" method that can be used instead. Be careful if you
// are working in an environment where it is possible that dojo/NodeList-html could
// have been loaded, since its definition of "html" will take precedence.
// The nodes represented by the value argument will be cloned if more than one
// node is in this NodeList. The nodes in this NodeList are returned in the "set"
// usage of this method, not the HTML that was inserted.

// if no value is passed, the result is String, the innerHTML of the first node.

// | <div id="foo"></div>
