That's dependent on the processor and on how you run the transformation. In
Saxon, if you reuse the same Transformer (doing a reset() between
transformations but not a clearDocumentPool()), then the documents
previously loaded using document() will still be in memory.

Alternatively, you can build the document cache yourself, and supply
documents from the cache in response to the document() call using your own
URIResolver.
