Good catch again. The OR is not supported. All AND cases are supported by nesting. Just to
answer case 3 (case 1 is very similar):

{code}
 <Delete baseDir="${sys:base}">
  <IfFileName glob="debug-*.log">
    <IfLastModified age="1d">
      <IfAccumulatedFileSize exceeds="100 mb">
        <IfAccumulatedFileCount exceeds="10" />
      </IfAccumulatedFileSize>
    </IfLastModified>
  </IfFileName>
</Delete>
{code}

I need to think about if/how to extend the OR (IfAny) syntax to support similar nesting.

> DefaultRolloverStrategy max attribute only applies if you have a %i in the file pattern.
This request is to enhance DefaultRolloverStrategy or another appropriate component to allow
a max number of files limit to apply across days/months/years when a filePattern includes
a date pattern.

> One of the most requested features is to add the ability to Log4j to "clean up" older
log files.  This usually means deleting these files, although it could also mean moving them
to a different location, or some combination of these. 
> Users have different requirements for selecting the files to clean up. A common request
is the ability to keep the last X number of log files. This works well if rollover is only
date based but may give undesired results with size based rollover. 
> Another factor to consider is that the directory containing the log files may contain
the log files for multiple appenders, or even files unrelated to logging.
