foo mod 10 mod 10 is the same as foo mod 10, and 10 mod 10 is 0 so the above is
<xsl:if test="($checkdigit + ((sum($odd) * 3) + sum($even))) mod 10 =0">
to give you the checkdigit? If so it makes the outermost "mod 10" of $calc redundant? (if it is then step #4 on the wikipedia article isnt needed)
