We're waiting to see how this works with Xalan-J before we do the same
thing in Xalan-C++, although I'm thinking this may be a very useful
enhancement.
It's not as pressing a problem with Xalan-C++ because there are all sorts
of tricks in C++ to minimize memory usage and the costs associated with
dynamic memory allocation that are not available in Java. We pretty much
make use of every trick in the book in Xalan-C++, so we can parse and
transform very large documents.
In Xalan-C++, the number of nodes in an XML document is restricted to the
maximum value of an unsigned long. On a 32-bit platform, that means
4,294,967,296 nodes. On a 64-bit platform, that would be
18,446,744,073,709,551,616 nodes, assuming an unsigned long is a 64-bit
value. I think you'd run out of memory address space well before you hit
either limit.

Hey, I never heard of this feature. Any chance this feature will be
implmented in xalan-c? Are there any restrictions to the number of nodes in
xalan-c?
