You can't, and that isn't my objective. What you can do, and what I
currently do with SAXON, is to perform a single serial pass of the input
document that simultaneously generates a TOC and the main rendered document
on two separate output streams, then merge these together for presentation.
This is far more efficient with a large document than building the entire
document tree in memory or scanning it twice.
