> The xsd schema definition for the log4j configuration allow only one AppenderRef per Logger. The definition of the Logger element is as follows
> {code:xml}
> <xs:complexType name="LoggerType">
>     <xs:sequence>
>         <xs:choice minOccurs="0" maxOccurs="1">
>             <xs:element name="Filters" type="FiltersType"/>
>             <xs:element name="Filter" type="FilterType"/>
>         </xs:choice>
>         <xs:element name="AppenderRef" type="AppenderRefType"/>
>     </xs:sequence>
>     <xs:attribute name="name" type="xs:string" use="required"/>
>     <xs:attribute name="level" type="xs:string" use="optional"/>
>     <xs:attribute name="additivity" type="xs:string" use="optional"/>
> </xs:complexType>
> {code}
> Comparing this to the Definition of the root Logger we see a sequence of multiple Appender
> Ref elements to be allowed.
> {code:xml}
> <xs:complexType name="RootType">
>     <xs:sequence>
>             <xs:element name="AppenderRef" type="AppenderRefType" minOccurs="1" maxOccurs="unbounded"/>
>     </xs:sequence>
>     <xs:attribute name="level" type="xs:string"/>
> </xs:complexType>
> {code}
> With this configuration it is not possible to define a specific Logger, that shows infos and errors to the console and writes only the errors in a log file, since there can only be one appender defined for that logger.
> Please modify the xsd file to allow mutliple AppenderRef elements per Logger.
