               Usage Example
               Allowed parents
               Allowed children
               Content model
               Namespace
            
         
         
            
               The description 
                  head element contains meta information about the enclosing 
                  
                     description
                      element.
                  
               
               The meta information in the description 
                  head element should not be treated as document content, but may be used for display and other purposes when rendering descriptions.
                  
               
               Although all metadata is optional, descriptions should, at a minimum, include an identifier, the intended reader age and/or
                  school grade level. See the 
                  DIAGRAM Descriptions Vocabulary for a set of predefined RDF properties. Properties from other RDF vocabularies can also be included, provided their prefix
                  is declared.
                  
               
               If age and grade-level metadata is omitted, the containing 
                  description should be assumed to be applicable to all readers.
