The 
                  quote element represents a quotation from a real or fictitious source.
                  
               
                When citing the source of a quotation, the 
                  
                     citation
                      must be explicitly linked to the 
                  quote by means of the 
                  
                     ref
                      attribute. 
                  
               
                If a 
                  quote element contains only a single child 
                  citation element, and the 
                  citation does not contain a 
                  ref attribute or child 
                  
                     ref
                      element, the association between the two elements is implied.
                  
               
               If a 
                  quote does not contain a citation, it can still be linked to the work it is cited from by attaching a 
                  
                     ref
                      attribute referencing an entry in a 
                  
                     bibliography
                     , for example. To reference other resources, including resources external to the current document, the 
                  
                     xlink:href
                      attribute must be used.
                  
               
               The 
                  
                     role
                      attribute optionally expresses the semantic nature of the quote. The 
                  role value 
                  epigraph, for example, indicates the quoted passage or verse represents an epigraph for the document or section.

               Note that in addition to restrictions presented in the content model  above, 
                  					use of this element must also respect the following requirement:
                  
                     - The 
                        
quote element must neither be empty nor contain only whitespace.
                        
                      
                  
                  Such requirements take precedence over any conflicting statements in the
                     						content model or in the lists above of allowed children and parents.
