Then I can't think of a way to help you do this in a single pass. I can't see how to express your requirement in a functional manner. You'll probably have to rely on a particular XSLT processor's extension function for modifying a global state variable.
If, however, you have the opportunity to do this in two passes, then on the first pass just seed the result with placebos, then use a modified identity transform for the second pass in order to trigger on the placebos encountered and implement your algorithm accordingly.
Remember that you can implement two passes in one stylesheet in XSLT 1.0 if you use an extension function such as exsl:node-set() to trap and reprocess the results of the first pass.
I hope this helps.
