Hi Brandon,
Your solution works wonderfully and was quite simple to render in the real code. Running it against almost 700 <Set>s flushed out two problems. One has to do with isolating formats to only stamps in which they occur, the other with label generation. I found no actual data that completely isolated the problem "Labels for different formats should be in different sequences; that is, each should start with 1". I can manufacture some if needed.

Attached is the original data, plus three additional <Sets>. I suspect Problem 1 is part and parcel of Problem 3, but included it in case my analysis was incorrect. The problems are identified in both the input and output data. In the stylesheet, I have removed the <StampPages> generating code because it worked perfectly.

Thanks again for all your help,
Mark

has been removed to make the problems
stand out better.

  Problem 1:
   Unlike the original data where there were two
   different se-tenants [105] and [107],
   here se-tenant has a single value [146];
   no label should be generated - see also
   Problem 3.
