How to add one day to the PaymentDate in XSL Template?

Need to add one day to the PaymentDate

-------------------------------------------------------

I am trying to customize XSL Stylesheet (HTML/XML/Text) tempalte, My requirement is add one day to the payment date, currently ReqdExctnDt xml tag is printing what ever payment date on transaction, see xsl syntax used in template.

<ReqdExctnDt>
   <xsl:value-of select="PaymentDate" />
   </ReqdExctnDt>

Is there any function i can use in XSL template file to add one day to the payment date, please suggest.

Thanks,
