Export dataset to WDF file format?

I am curious if there is something missing from the documentation related to exporting Dataset objects created from a simple Association. On the documentation page for WDF, it indicates that datasets can be exported and imported in WDF. When I try it, I get a failure.

In[49]:= Export["/Users/matt/test.WDF", dx]

During evaluation of In[49]:= Export::infer: Cannot infer format of file test.WDF.

Out[49]= $Failed

Explicitly adding "WDF" as the export format didn't help either. Then I noticed that WDF was not included in the supported export formats:

In[50]:= $ExportFormats

I'm a bit lost - the documentation indicates that WDF is a valid format, but it's not in the list. I'm using Mathematica v11.3 on macOS Mojave.

I think the “WDF” means something else in Mathematica.

Wolfram Data Framework (wdf)



That documentation is why I asked. From the linked page:

Exporting WDF
Export — export WDF to a file (.wdf, .wdf.nb, .wdf.json, etc.)

That, along with the discussion of datasets and associations on that page, implies some export functionality that doesn’t seem to work.
