In DSSSL, such a thing was not possible because there were
unpredicatable dependencies -- for example, you might find this near
the front of the document:

  <gloss id="x">...</gloss>

But you wouldn't know that you had to do something useful with it
until you found this near the end of the document:

  <annotation source="x">...</annotation>

In the general case, then, a stream-based DSSSL processor would
*still* have to cache the entire document, since it allowed arbitrary
navigation.  I don't know if the same applies to XSL -- I'll have to
give the spec a closer look.

All the best,
