+/**
+ * A generic grouping transform for schema {@link PCollection}s.
+ *
+ * <p>When used without a combiner, this transforms simply acts as a {@link GroupByKey}
but without
+ * the need for the user to explicitly extract the keys. For example, consider the following
input
+ * type:
+ *
+ * <pre>{@code
+ * {@literal @DefaultSchema(JavaFieldSchema.class)}
 
 Review comment:
   I think `@literal` is unnecessary within `@code`
