Section 2.6.1.3 contains a mention of xsi:type, treating it as if it
modified the mapping function from lexical values onto values of a union
type. This would mean that the mapping from lexical space to value space is
not actually a simple function as described in 2.4: it becomes a function
that takes two parameters, the lexical value and the value of xsi:type. It
would be better to treat xsi:type not as "overriding the evaluation order",
but rather as causing a different datatype, and hence a different mapping
function, to be invoked.
