22   
23      This class defines an interface to logger.XmlWriter that's compatible 
24      with python's logging module. Note that logger.XmlWriter expects to write 
25      a complete log from start to finish. This is because it attempts to produce 
26      well formed XML. It also employs some compression filters that don't 
27      define an append mode, so not allowing append is more consistent. This 
28      deviates from normal python logging assumptions. Use with caution."""
