Someone will object that the sequence of sequences I claimed was my
goal will be flattened. What I really want as output is something like
<span>This text has <i>italics</i> and</span>
<span>an embedded ref</span>
so I'm really looking sequentially for node sequences defined as either
(1) a single <ref> or (2) a sequence of one or more non-<ref> nodes.
