There IS a difference between the two scenarios that you 
lay out John. On the one hand you (or your company) assembles
a number of products into a rack for a specific function and that
function is internal. 

On the other hand you have a manufacturer who decides (with the exact
same set of products) to place that solution on the market. If the
manufacturer markets that solution (with a Model number or equivalent)
then the manufacturer is responsible for the EMC/Safety of said system.

Without testing - how does the manufacturer demonstrate compliance
to the EMC or Safety directives?

I have had to work rack mount solution issues on other companies and we
simply couldn't find a way that the company was not held responsible to
the directives.

Is there a guideline published anywhere that we can reference?

I understand your point, but I believe that the actual situation is as I

have explained it.  It simply doesn't make sense that I (my company) can

buy a number of products and put them on a shelf, or even install them 
in a rack, without any EMC issue being raised, but if the manufacturer 
puts then into a rack for me, he has to spend $$$$ having the rack 
tested for EMC, and indeed it may not pass, because the acceptable 
emissions form the items add up to exceed a limit.
