Buffering Questions

Hi,
The following questions are about FileAppender and AsyncAppender buffering:

1. I found an example of how to configure the FileAppender to buffer the 
logging events:

    <param name="ImmediateFlush" value="false"/>
    <param name="BufferedIO" value="true"/>

    (a) What's the difference between buffering and not-flushing (are there 4 
distinct combinations I can configure?)
    (b) Is there a way to configure the buffer size? (from script that is)

2. I could not find an example in the log4cxx side (there might be one on the 
java side) of how to configure the buffer size
    for the async appender.
    (And in general, is there a place where one can find the complete dtd in 
use?)

Many thanks,
Barak
