Can valang create dependency controls?

[a_subscriber]

my spirng config

		<property name="valang">
			<value>
				<![CDATA[
					{ name : ? HAS LENGTH : 'Profile name is required' : 'required.profileName' }
					{ name : ? IS BLANK OR length(?) <= 30 : 'Profile name must be no longer than {0} characters' : 'proflieName.length': 30 }
				]]>
			</value>
		</property>

It's work. OK, but I want if first control (is empty) is false then NOT check second control (length). Is this possible in the valang?
