RE: What does the phrase "duplicates removed" mean pr

No, when the spec speaks of duplicates it's generally talking about node identity, not content. People sometimes use the phrase "two nodes with the same identity" - I try to avoid that, because you've then got one node, not two. A sequence contains duplicates if it contains the same node twice: for example, with <root> in the above example as the context node, the sequence (child::SomeTag, descendant::SomeTag) contains four items, namely two occurrences of each of the two SomeTag nodes. If you replace the "," operator with "|", duplicates are eliminated, and you end up with one occurrence of each of the two SomeTag elements. Michael Kay http://www.saxonica.com/
