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 can be used in place of the element . For instance, the following are equivalent: 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.
