           Summary: [FS] technical: 4.1.5 Function Calls: complicated by
           Product: XPath / XQuery / XSLT

4.1.5 Function Calls

"Otherwise, the function signatures matching the function name and arity
are retrieved from the static environment."
    The XQuery and XPath specs both state:
        "Each function is uniquely identified by its expanded QName
        and its arity (number of parameters)."
    So am I correct in thinking that there would be *multiple* signatures
    only in the cases of the "arithmetic operator pseudo-functions" and
    the "comparison pseudo-functions"?

    Is it also true that the "union of atomic types" exceptions in the STA
    are only relevant to the pseudo-functions? (I.e., for any other call,
    you'd get the same result if those exceptions weren't there.)

    If so, then details that are only pertinent to pseudo-functions are
    being allowed to complicate the normal case. Why? It seems to me that
    this section would be much improved by banishing those details to B.2.
