The glossary 
                  entry element represents a single unique entry in a 
                  
                     glossary
                     .
                  
               
               A glossary 
                  entry must contain one or more 
                  
                     term
                      elements and either one or more 
                  
                     definition
                      elements or one or more 
                  
                     ref
                      elements pointing to a 
                  definition.
                  
               
               To facilitate the markup of glossaries, if an 
                  entry contains exactly one 
                  term and one 
                  definition an implicit association is assumed between them (i.e., the normal requirement to explicitly link the 
                  term to the 
                  definition by the 
                  
                     ref
                      attribute does not apply). If the 
                  entry contains mutliple 
                  term or 
                  definition elements, then the explicit association of each is required.

               Note that in addition to restrictions presented in the content model  above, 
                  					use of this element must also respect the following requirements:
                  
                     - Each 
                        
entry element must contain at least one 
                        term element.
                        
                      
                     - Each 
                        
entry element must contain at least one 
                        definition or 
                        ref element.
                        
                      
                     - Each 
                        
term element must explicitly reference its 
                        definition(s) when more than one 
                        term or 
                        definition are included in the 
                        entry.
                        
                      
                     - Each 
                        
entry element must contain at least one 
                        definition or reference to a 
                        definition.
                        
                      
                     - The 
                        
entry 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.
