  Well I would answer no. Depends what you mean by incremental. Currently
libxslt generates an output tree and then that tree is serialized in a
second step. Most processors actually serialize as soon as possible and
don't really build the output tree. From that view point, libxslt doesn't
work in an incremental fashion. That could be added but it's not trivial.
