Not easily. XML Schema doesn't support a 64 bit type (at least it didn't when we defined the interfaces.

 

 

We contemplated using strings and just passing the values around that way but that has other problems with non-64 bit enabled clients being able to decipher them. Other issues we ran into was the signed/unsigned issue with the high/low values. Java doesn't support an unsigned type (again, at least at the time of designing the interfaces) so when we returned the values as an unsigned long schema type, java threw exception after exception and just wouldn't work.

 

 

So, unfortunately, to support every toolkit out there, we are stuck with some limitations. One of them being the low/high 32bit value pairs for the statistics.

 

 

Keep in mind that you can always "chunk" your requests to smaller sizes. That won't reduce overall bandwidth usage, but it will make single responses smaller.
