Is it possible to have multiple handlers with same category in jboss-7 logging?

I have defined two handlers for category with same name in standalone.xml file, like below 

<logger category="ab.cd" use-parent-handlers="false">
            <level name="DEBUG" />
            <handlers>
                <handler name="abDebug" />
            </handlers>
        </logger>
<logger category="ab.cd" use-parent-handlers="true">
                <level name="WARN" />
                <handlers>
                    <handler name="abWarning" />
                </handlers>
            </logger>

But i am getting exception when i try to run jboss 7

 14:28:08,090 ERROR [org.jboss.as.server] JBAS015956: Caught exception during boot: org.jboss.as.controller.persistence.ConfigurationPersistenceException: JBAS014676: Failed to parse configuration

You can't have two loggers with the same category defined. How would the logger know which level it's supposed to use? You're best to use one logger with no level set and use the handlers to set the level you want to be logged.

Something like the following:

<file-handler name="abDebug" auto-flush="true">
    <level name="DEBUG"/>
    <file relative-to="jboss.server.log.dir" path="abDebug.log"/>
    <append value="true"/>
</file-handler>
<file-handler name="abWarning" auto-flush="true">
    <level name="WARN"/>
    <file relative-to="jboss.server.log.dir" path="abWarning.log"/>
    <append value="true"/>
</file-handler>

<logger category="ab.cd">
    <handlers>
        <handler name="abDebug" />
        <handler name="abWarning" />
    </handlers>
</logger>
