Well, I would either think an

<if test="...">
xml snippet
</if>

construction, where the snippet was only evaluated if the test was true, or

<appender-ref ref="..." if="${enable.appender.FOO}">

would be nice. 

In any case it would be nice if this mechanism could be used to avoid 
constructing unreferenced appenders, as I understand that they are 
created when seen in the configuration process.

(Oh, and I found that changes in FileAppender options (changing true to 
false, etc) are not picked up when reloading default configuration over 
JMX).
