Date:   November 7th, 2008
Rev:    1.01
Usage:  You only need to add the following to the log4net element:
        <log4net 
          xsi:noNamespaceSchemaLocation="http://csharptest.net/downloads/schema/log4net.xsd" 
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

Preface:
Please be aware that though this xsd attempts to cover most of the usages you 
will encounter with log4net configurations it is by no means complete.  The 
primary reason (excuse) for this is that the xml format used by log4net config 
files does not conform to any real standard.  This is both it's primary 
weakness and it's strength.  As such there are a few things you should know
about how log4net interprets your configuration before creating one.

Firstly most of the elements described in this document are really not needed.  
This is due to the fact that a <param name='x' ...> can be used in place of
the element <x ...>.  For instance, the following are equivalent:
    <maximumFileSize value="1MB" />
    <param name="maximumFileSize" value="1MB" />

So Why Use This Xsd?:
This xsd attempts to utilize the former convention and to declare as much as
possible for the benefit of auto-completion and sanity checking.  However, 
since most of the param names vary by the containing element's 'type' attribute 
it is impossible to describe this correctly in xsd (at least to my knowledge).  
So use this schema if you like and remember that there is life beyond it's 
limited capability.

If you would like to contribute back to this schema you can send email to the
follow address (remove all the spaces and slashes): schema / @ / csharptest.net
Be sure to include the schema name "log4net.xsd" in the subject-line.  If you
know someone on the log4net project please convince them to adopt a schema,
I don't care which one, just have one.
