I meant: "In DSSSL, basically only nodelists (and sosofos?) are defined
such that their implementations can be lazy" but I got lazy. For
instance I would be surprised if an implementation of node-list->list
resulted in a lazily-created Scheme list. Am I being overly pessimistic?
Would the original DSSSL (before we may or may not add side effects)
permit lazy creation of Scheme lists?
