No, extending class is not complicated, I have already done some
Appenders etc. I can create the descendant of the PatternLayout with
hard-wired pattern without problem.
But what I can't imagine is how to create PatternLayout descendant in
the manner of my original question. Layout, which is "detached", which
is configurable from XML and is referable in the same way as appenders.
Example "MySharedLayout" bellow. Is this realizable by me?
<layout type="Company.Logging.CustomisedLayoutPattern, Company.Logging"
name="MySharedLayout">
<conversionPattern value="%date [%thread] %-5level %-35.35logger
[%-10.10property{NDC}] - %message%newline" />
</layout>
<appender name="Global.FileAppender"
type="log4net.Appender.RollingFileAppender">
<layout-ref ref="MySharedLayout">
</appender>
