Oh boy, there's certainly a can of worms here. Comparing this section to
3.11.4 from V1 (http://www.w3.org/TR/xmlschema-1/#d0e13803), there are a number
of what at first appear to me to be unmotivated changes. The most important of
these is the change from "a node-set with exactly one member" in the definition
of *qualified node set* to "a node sequence one of whose members", which seems
to me to depend too obscurely on the implicit uniqueness arising from item 3 in
the preceding list.
Would the following be a) correct and b) simpler?
3) For each node *N* in the ˇtarget node setˇ, for each *F* of the {fields},
define *NS(N,F)* as the sequence of nodes that *F* evaluates to with *N$ as the
context node (as defined in XPath Evaluation (§3.13.4.2)). *NS* consists of
zero or more ˇskippedˇ nodes and at most one node with a non-ˇabsentˇ [schema
actual value]. [Definition:] Define the key-sequence of *N* as the sequence of
[schema actual value]s of those nodes in *NS(N,F)* which have one for each *F*,
in order.
