 I'm not sure it is really a grouping problem, though it is related. But I can tell you where your script fails. I suspect you use the following line to determine the distinctness of some item/@id, but it obviously fails: <xsl:if test="not(preceding-sibling::item/@id = $pass_id)"> At least one problem is that the preceding-sibling does not go up the section element an down a preceding section. Use the preceding axis for this. But I tried and this also doesn't seem to work and I haven't figured out why exactly. But I did come up with a solution (see below) that builds an index on what you are searching and uses that index to determine whether an item with a specific @id value is the first in document order or not. The xsl:key defines the index, which contains a rather complex match expression, but this expression merely combines your own if and foreach in the item template. The tricky part comes in passage2 template, where I use generate-id to determine whether the first of all OE-items with the same id is actually the current item. Only the first in document order is printed.
