More Complex Example of Aggregating Modifiers in DTDs

Following is a more complicated example. Suppose you want book elements to include

To accomplish this, you would perform steps that generate the following tree representation:

book
               

              

                
Sequence
                   
title
                   
Optional
                   
	Choice
                   
		author
                   
		editor
                   
Zero or More
                   
	paragraph
                   

                
              

            

In the Text view of the DTD, the definition for the book element is as follows:

<!ELEMENT book (title, (author|editor)?, paragraph*)>
