Saxon's two native tree implementations (the standard tree and the tiny
tree) are both read-only - they are designed for XSLT processing, where
node-level updates are not a requirement, and making the structures
read-only allows higher XSLT performance.
The only mutable tree structure that Saxon supports is the JDOM
I believe that some Saxon users have written drivers that allow Saxon to
be used with third-party DOM implementations, but there's no such driver
included with the product.

In the case of JDOM, you build the tree using JDOM interfaces.
In the case of Saxon's two tree implementations, you can control it
using a property of the TransformerFactory.
