Hello, the specifications for fn:avg, fn:max, fn:min, and fn:sum don't say what all of these functions return if the argument is a sequence containing only NaNs. Either the specification must define, that if after discarding these NaNs no other values remain (i.e. an empty sequence) then the empty sequence is returned. (Short "If $srcval contains exclusively NaN values then the empty sequence is returned.") Or the whole discarding rule is dropped (I noted already a compatibility problem for fn:sum), and the definitions have to be rephrased properly (e.g. for fn:min "... the item in $srcval whose value is not greater than the value of every other item ..."), thus, if a NaN value is in $srcval then the result is NaN.
