Those changes are improvements, but I think there's still the problem,
raised in comment #9, of the wording:
    Numeric and xs:anyURI values are converted to the least common type...
The question is: the least common type of what?  I claim that a plausible
answer is:
    the least common type of the numeric and/or xs:anyURI values
    in the input sequence
(i.e., the values identified in the sentence's subject), which leads to
unintended results. In comment #10, you say that your reading is:
    the least common type of all the items in the input sequence
which I say is a non-obvious reading.

Moreover, I believe the wording still indicates that, if you call the
function with a sequence of xs:anyURI values and a collation, the values
are compared using the default collation, not the supplied collation.
I'm still wondering if that's intended.
