Passing value in error message

[Muhammad Owais <mu...@yahoo.com>]

Dear;
I am looking for a solution to pass value as parameter to the error message.
What I want to achive is that I have to validate Date field. This date field's validation is of general type and with the concept of re-useablity. 
The validation rule(s) is like the date should be greater then current date + 5 minutes. The validation rule parameter can vary with 5, 10, 20 ...
So what I did is:			<field property="startDate" depends="isFutureDateMinutes">			
	<arg position="0" key="label.startDate" />				<arg position="1" name="futureMinutes" key="${var:inFutureMin}" resource="false" />				<var>					<var-name>dateformat</var-name>					<var-value>dd/MM/yyyyHHmm</var-value>				</var>				<var>					<var-name>minutesofhour</var-name>					<var-value>startDateMinutes</var-value>				</var>				<var>					<var-name>inFutureMin</var-name>					<var-value>5</var-value>				</var>			</field>
I want to use inFutureMin value in my error message.
Please recommend how can I do it.  

Thanking you in advance.
