<!-- A configuration element consists of optional renderer
elements,appender elements, categories and an optional root
element. -->

<!--
    category instead of logger cannot be used. categoryFactory is not implemented in log4php.

<!-- The "threshold" attribute takes a level value such that all -->
<!-- logging statements with a level equal or below this value are -->
<!-- disabled. -->

<!-- Setting the "debug" enable the printing of internal log4j logging   -->
<!-- statements.                                                         -->

<!-- By default, debug attribute is "null", meaning that we not do touch -->
<!-- internal log4j logging settings. The "null" value for the threshold -->
<!-- attribute can be misleading. The threshold field of a repository    -->
<!-- cannot be set to null. The "null" value for the threshold attribute -->
<!-- simply means don't touch the threshold field, the threshold field   --> 
<!-- keeps its old value.                                                -->
