Looking at that code again I think it should be rewritten to use map:for-each it's too convoluted, but it probably gives you an idea of how to proceed. Here's a test that shows how it works. https://github.com/xokomola/fold/blob/dbb79c60a7356e32a0994e581ad4f7f5377ddc72/test/fold-common/test-common.xqm#L166 --Marc
