Struct NullSax 

pub struct NullSax;

A handler that discards every callback, using the trait’s default bodies.

Building a tree does not need the SAX event stream, but the tree entry points used SaxRecorder, which deep-copies the local name, prefix, URI, namespace list and every attribute of every element into a log that is then dropped. On a 627 KB document that was over half of all allocations.
