   Above +org.mycompany.root+ transitively defines 3 sections:
  
positive.code: configuration:
  
  . the _configuration section:_ In our case this equals to +a.b.c+, which itself also includes the
   tranitive entries +a.b+ and +a+.
  . the _configuration parameter:_ Basically parameters are adressed using their fully qualified names,
   which equals to the containing section name and the relative parameter name, separated by the dor separator.
   In the above example +a.b.c.param1+ and +a.b.c.param2+ are the fully qualified parameter names.
  
negative.code: 
  The model module provides different switches that can be used to activate or deactivate features:
  
  * +tamaya.model.integrated.enabled+ allows to deactivate reading inline metaconfiguration delivered with
    the normal Tamaya Configuration. By default inline entries (+_.abcd.model.*+) are evaluated.
  * +tamaya.model.default.enabled+ allows to deactivate reading metamodel information from
    +classpath:META-INF/configmodel.properties+. By default it is active.
  * +tamaya.model.resources+ allows to define additional resources (loaded through the resources extension),
    that can be used to read metamodel information in any format using Tamaya's format module.
  * the system property +tamaya.model.autoModelEvents+ allows to activate/deactivate the automatic
    documentation of classes configured and published by Tamaya +ConfiguredType+ event instances (e.g. published by
    Tamaya's injection modules).
