   8 [section:IoObjectService I/O object service requirements]
   9
  10 An I/O object service must meet the requirements for a [link
  11 boost_asio.reference.Service service], as well as the requirements listed
  12 below.
  13
  14 In the table below, `X` denotes an I/O object service class, `a` and `ao` denote
  15 values of type `X`, `b` and `c` denote values of type `X::implementation_type`,
  16 and `u` denotes an identifier.
