Thanks, Darin; It sounds like you are saying that weighting is driven by the existence of an index, and there is no index applying to "an element and all its descendants". Is that really true? Anyone from Mark Logic want to weigh in?

For cts:element-query, TF and IDF are based on the entire document (fragment). At least that is my understanding.
