Xinha config is not bootstrapped: unrecognized delta semantics

Create a clean archetype project, with all the default properties. Start it with mvn -Pcargo.run. This info message appears in the logs:

[INFO] [talledLocalContainer] 14.10.2013 09:03:24 INFO main [InitializeItem.initContentResourceValues:205] Content resource configuration/richtextconfig/xinha.xml uses unrecognized delta xml semantics; export in this context will be disabled.

Indeed the config data in \bootstrap\configuration\src\main\resources\configuration\richtextconfig\xinha.xml is not bootstrapped. Or this file should go, or the delta semantics should be improved.
