9.  number_of_operations
      This value is the number of operations contained in an instruction.
      /For conventional processors, this may be zero or one.  For VLIW
      processors which have multiple operations in each instruction, this
      value is the number of operations in each instruction./

  10. operation_sizes (array of ubyte)
      There are number_of_opeations entries in this array.  Each entry 
      gives the size of the corresponding operation in bits.  Operations
      are ordered within the instruction by increasing machine address.  

'operations' not opeations.

It's not entirely clear if the 'array of ubyte'   would have zero 
entries if number_of_operations
is zero.  One would think so, but IMO it should be said.

It's not clear why 'array of ubyte' is better than 'array of uleb' (one 
that for known processors these would have the same representation bits).
