* \class DOMTextNode
* \brief Class to represent a special DOM node that holds a text string.
*
* A text node has no attributes and children. So a text node is always a leaf node,
* and the special attribute "id" cannot be used.
* In this implementation, a text node is internally represented using a special tag name of "!".
* This is not a problem as "!" is not a valid tag name in any XML file.
