| implementationName | implementation name of server | 
         
          | implementationVersion | implementation version of server | 
         
          | implementationId | implementation ID of server | 
         
          | schema | schema for retrieval. By default, no schema is used. Setting this
           option is equivalent to using function 
           yaz_schema() | 
         
          | preferredRecordSyntax | record syntax for retrieval. By default, no syntax is used. Setting
           this option is equivalent to using function 
           yaz_syntax() | 
         
          | start | offset for first record to be retrieved via 
           yaz_search() or yaz_present().
           First record is numbered has a start value of 0. Second record has
           start value 1.
           Setting this option in combination with option
           count has the same effect as calling
           yaz_range() except that records are
           numbered from 1 in yaz_range() | 
         
          | count | maximum number of records to be retrieved via
           yaz_search() or yaz_present(). | 
         
          | elementSetName | element-set-name for retrieval. Setting this option is
           equivalent to calling yaz_element(). |
