	abstract = {
        We introduce a controlled form of recursion in XQuery,
        inflationary fixed points, familiar in the context of relational
        databases. This imposes restrictions on the expressible types of
        recursion, but we show that inflationary fixed points
        nevertheless are sufficiently versatile to capture a wide range
        of interesting use cases, including the semantics of Regular
        XPath and its core transitive closure construct.

        While the optimization of general user-defined recursive
        functions in XQuery appears elusive, we will describe how
        inflationary fixed points can be efficiently evaluated, provided
        that the recursive XQuery expressions exhibit a distributivity
        property. We show how distributivity can be assessed both,
        syntactically and algebraically, and provide experimental
        evidence that XQuery processors can substantially benefit during
        inflationary fixed point evaluation.
