It's really not April 1, is it?

Hi Folks,
I think XML tools (e.g., XML parsers, schema validators, XSLT processors) should handle XML files up to 2^64 bytes in size.
2^64 = 18,446,744,073,709,551,616 (20 digits)
Why that number? Here's why:
The number 2^64 is:
The number of distinct values representable in a single word on a 64-bit processor. Or, the number of values representable in a doubleword on a 32-bit processor. Or, the number of values representable in a quadword on a 16-bit processor, such as the original x86 processors.
The range of a long variable in the Java and C# programming languages.
The range of a Int64 or QWord variable in the Pascal programming language.
The total number of IPv6 addresses generally given to a single LAN or subnet.
Thoughts?
