If you ouput results as SAX rather than requesting that a DOM be built,
that will be incremental.
Your problem is probably the input tree. The input tree can be built
incrementally, but there isn't currently any automatic flush meachanism.
We do hope to add that; see archives of this mailing list for comments
about "pruning". Unfortunately pruning is significantly harder in DTM than
it was in earlier source-tree representations.
Note too that DTM has a maximum document size that it doesn't want to
exceed. We're considering raising that, but there's some risk that your
100M file may need more nodes than we can handle.
