It might be a debian patch setting it as the default.


How about:

   <para>
    In its default configuration <productname>FOP</productname> will emit an
    <literal>INFO</literal> message for each page. The log level can be
    changed via <filename>~/.foprc</filename>:
<programlisting>
LOGCHOICE=-Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog
LOGLEVEL=-Dorg.apache.commons.logging.simplelog.defaultlog=WARN
</programlisting>
   </para>

Ah, good.

Yea, looks like the span="inherit" one is harmless and known:

https://issues.apache.org/jira/browse/FOP-1534

We could silence it in our stylesheet, but it's probably not worth bothering.
