    field:
    
    type (required):   dynamic or constant. If you choose dynamic, then the field
    value is read from the row in the ResultSet returned
    from the database. If constant, then each returned row
    from the ResultSet is annotated with the value specified
    in the 'value' attribute.
    
    name (required):   the name of the attribute that you want returned
    in the product server.
    
    string (optional): whether or not the internal db representation at the local
    site for this field is a STRING, or something else (e.g., a number, etc.). Possible 
    values for this attribute are "true", to indicate that the field is a string, or
    "false", to indicate that it is something else. If this attribute is omitted, a value
    of "false" is assumed, and the attribute will not be quoted in the where clause of
    the underlying SQL statement generated.
    
    dbname (optional): the name of the field within the underlying db. If not
    specified, then assumed to be name
    
    table (optional):  if provided, then the attribute a is selected as
    'table'.'a',and then returned. If omitted, the attribute
    is assumed to come from the default table returned from the
    PS query.
    
    value (optional):  is necessary to provide if type='constant' is selected.
    
    scope (optional):  limits the scope of a field's existence: acceptable values
    are &quot;query&quot;, which signifies that the field is only applicable when
    translating queries: and &quot;return&quot;, which signifies the field is only
    applicable as a return field when converting database results into CDEResults.
