There is no updateable variables in XSLT.

But there is general pattern for 'counter' :

template accumulator ( list ) {

    $first element = take first element of the list ( position() = 1 )
    $rest list = take the rest of the list ( position() > 1 )

    $total-of-rest  =  {
            if ( $rest ) { 
                 call accumulator(  $rest )
            } else {
                <!-- nothing. End of loop. -->
            }
    }

    <xsl:value-of select = " $first + $total-of-rest " />
}


Invokation: 

template( list-to-process )

PS. I wish I understand the question.
