I think Xalan-J 2.0.0 had a bug.

As Joanne pointed out, the syntax for a number in XPath 1.0 doesn't permit "E" 
notation.[1]  Further, when the type of an argument is expected to be of type 
number, the argument is converted as if by the number function.[2]

According to the description of the number function [3], "a string that 
consists of optional whitespace followed by an optional minus sign followed by 
a Number followed by whitespace is converted to the IEEE 754 number that is 
nearest (according to the IEEE 754 round-to-nearest rule) to the mathematical 
value represented by the string; any other string is converted to NaN."  So, a 
string value like "2.090699555E7", when converted to a number using the number 
function, explicitly or implicitly, has the value NaN.

If you require other syntactic forms for numbers, you might be able to use a 
Java extension, or write a template that parses the value as Joanne described.

I hope that helps.
