Michael, Phil, thanks! I didn't know about floor() function in XSLT/SLAX. However, looks like in extremely rare cases math:random() can return 1 because according to https://github.com/GNOME/libxslt/blob/master/libexslt/math.c#L465 random number calculation can be "(double)RAND_MAX / (double)RAND_MAX". So final solution should be "floor(math:random() * 16) mod 16".
