Do long element names impact performance?

Hi Folks,

Is the following true or false? 

	XML developers who fail to grasp the distinction between reading and evaluating 
	an XML instance document may have a good model of the structure of XML, 
	but they usually have a terrible model of the efficiency of processing XML. One 
	XML developer used only one-letter element names, because he felt that it would 
	be faster for the computer to look up one-letter elements than a multi-letter name. 
	While it may be true that shorter names can save a microsecond at read time, this 
	makes no difference at all at evaluation time. Every element, regardless of its name, 
	is just a memory location, and the time to access the location does not depend on the 
	name of the element.
