Figured I'd finally chime in...

Everything, from Elements which have only text, to Elements which have
mixed content, has a textual representation, which is use heartily in

    I like <b>cheese</b>

The text, in xpath realms of thinking, is "\nI like cheese\n"
It's a recursive evaluation of the text of all descendants.

I certainly don't think that setText(...) should be recursive,
so for symmetry, getText() should not be either.

But, there is obviously a call from some folks to have a recursive-esque
getText() functionality.

So, maybe a getXPathText(), or a getText(boolean recurse).

	String getText() 
	    return getText(false); 

	String getText(boolean recurse) 
	    if ( ! recurse ) 
	        return this.text;

	    ... return complex recursive assembly of text ...
