/* Version   Description
 *   1       first version until June 07; implicite, not tagged
 *   2       introduced June 07, enhanced/cleaned/arranged structure
 *   3       2007-11-15 RAW DDL data type added; some inconsistencies fixed
 *           ('void' and 'any' origins); added signed HLT basic data types
 *           2007-11-23 origin defines have become variables in conjunction
 *           to be used with the operator| (AliHLTComponentDataType)
 *           2007-11-24 added trigger structs and ESD tree data type
 *   4       Component configuration and DCS update events added
 *           gkAliHLTDDLListSize set from 29 to 30 according to new PubSub
 *           specs
 *   5       Data types for Run and Event summary, and for monitoring added
