  +=== Field optionality
  +
  +All fields in all blocks (unless field is array) are mandatory. However default
  +value (which usually is 0) is specified for each of the tags, if any. Thus in
  +that particular case, if field is not received form network, the default value
  +is used.

  +== Complex data type blocks
  +
  +This section list complex data type blocks which are later incorporated in the
  +message blocks.

  +=== Multi-buffer block (array of) for XATMI call data transport

   As Enduro/X may send several buffers with one request, for reasons of call info
   data, primary buffer and and primary buffer is UBF it might have embedded VIEW,
   UBF objects or UBF might contain pointer to other buffers. Thus multiple XATMI

negative.code: Where we can look on structure like a complex data type. Each structure may
  consist of basic data types or complex data types. Which makes messages a
  hierarchical tree of the structures. Where leaf structures always consists of
  basic data types. This document uses term "block", "complex data typed block", "message blocks" 
  and "structures" with the same meaning.
  
  Basically network messages consists of the message blocks. These message blocks
  then are constructed basic data types and complex data type blocks.
  
  
  Typical message layout would be:
