validator intRange

Hi!

I need to validate integer value entered in 'year' field. This fied can be emty as well.

I use following rule in validation.xml
      <field property="year" depends="integer,intRange">
        <msg name="integer"  key="validator.numeric"/>
        <arg0 key="resumeBuilder.birthDayYear"/>
        <arg1 name="intRange" key="${var:min}" resource="false"/>
        <arg2 name="intRange" key="${var:max}" resource="false"/>
        <var>
          <var-name>min</var-name>
          <var-value>1900</var-value>
        </var>
        <var>
          <var-name>max</var-name>
          <var-value>2100</var-value>
        </var>
      </field>
But such rule doesn't allows me to leave this field empty. If I insert zero instead min value in rule declaration, than everything is ok, but it is not a solution for me. How can I use range limitation and allow to user leave this field empty using validation.xml rules.

Maxim.
