"1. If the operand is a sublist, the entire sublist and each entry of the
sublist can possess attributes. The whole sublist has the same attributes

as those of the first suboperand in the sublist (except for the count
-----------------------------------------------
attribute, which can be different, and the number attribute which is
relevant only for the whole sublist)."

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.
I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.
