Multiple JobParameter validators

[sseaman]

I'm curious why multiple job parameter validators are not allowed?

I want to validate that job parameters exists as well as them being a certain format. Why can't I do something like:

<beans:bean class="org.springframework.batch.core.job.DefaultJobParametersValidator">
	<beans:property name="requiredKeys">
		<beans:list>
			<beans:value>someKey1</beans:value>
			<beans:value>someKey2</beans:value>
		</beans:list>
	</beans:property>
</beans:bean>
<beans:bean class="com.xxxxx.batch.validation.FormatJobParametersValidator">
	<beans:property name="keys">
		<beans:list>
			<beans:value>someKey1</beans:value>
		</beans:list>
	</beans:property>
	<beans:property name="format">
		<beans:bean class="java.text.SimpleDateFormat">
			<beans:constructor-arg value="yyyyMMdd"/>
		</beans:bean>
	</beans:property>
</beans:bean>

This way I could use the existing code and add additional format validation whenever I want.

I understand that I could extend the Default and add my format validation (which is what I will do to get around the existing limitation), but I'm curious why the above isn't supported.
