Sure!
Given a DoFn that has...
def process(self, sentence):
yield from sentence.split()
You could use it with SchemadParDo as:
(p | beam.Create([pvalue.Row(element="hello world", id="id")])
| SchemadParDo(SchemadParDo(SplitSentenceDoFn(), input_field="element",
output_field="word"))
And it'd produce Row(word="hello", id="id") and Row(word=""world", id="id")
