Yes it will be possible to use the PatternString to set the value of any
string property in the configuration using the following example syntax:
<file
type="log4net.Util.PatternString"
value="%property{BIN_DIR}\\..\\logs\\Application.log" />
We may look at ways of making this simpler so that the type attribute
does not need to be specified.
