[logback-user] Job Logger configuration

I hear ya on the sifting appender only accepting 1 key.  And I changed
the jobId to  MDC.put("fname",jobGroup+"/"+jobName+"/"+jobId ); which
does work with the following configuration:
 <appender name="jobLoggerAppender"
class="ch.qos.logback.classic.sift.SiftingAppender">
    <discriminator
class="ch.qos.logback.classic.sift.MDCBasedDiscriminator">
         <key>fname</key>
        <defaultValue>unknown</defaultValue>
    </discriminator>
        <sift>
            <appender  name="SIFT_INTERNAL"
class="ch.qos.logback.core.FileAppender">
            <prudent>true</prudent>
                <file>${fname}.log</file>
                  <encoder
class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
                        <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level
[%thread] %C:%L %msg%n</pattern>
                    </encoder>
            </appender>
        </sift>
    </appender>

What concerns me is that I don't seem to be able to override the
MDCAdapter that logback uses for the sifting.  The documentation says
that the class="..." attribute should override the MDCAdapter
implementation used.  but it doesn't.  No matter what I put in that
class attribute, it always uses
ch.qos.logback.classic.util.LogbackMDCAdapter

I looked at the source for that MDCAdapter implementation and have
confirmed that it does only use one value but that the MDCBasicAdapter
from slf4j supports multiple keys.  What is preventing me from using the
better implementation from SLF4J?
