XPath/XQuery - Typed Value Determination

I'm confused by the wording of...

    http://www.w3.org/TR/xpath-datamodel/#TypedValueDetermination

    ...where it discusses the value value determination for lists.

    "For each of these lexical forms, the type of the corresponding
    item is found in {item type definition}."

    I can't figure out if the {item type definition} is attached to
    the list as a property, or an index property, or if it attached
    to the item within the list. The mention of recursion implies
    the latter.

    Thank you.
