What advantage is there in encapsulating a Tiff in DNG?

Literally using DNG as a container for the TIFF data, you retain the
benefits of DNG WRT user edits but of course it can't strictly be
developed like a RAW Bayer mosaic file.

Not sure what you mean by 'encapsulate it in DNG'.

A sad misunderstanding from the early days of digital. TIFF in camera is
an 8bit RGB format and essentially no better than JPEG except for the
lack
of compression losses.
You can never return an RGB format to mosaiced raw data, but you can
encapsulate it in DNG. It does benefit from some standardization, but
little
else.

Herb Keppler (I think it was him) did a review of the *ist-D and he

that since the camera offered TIFF as one of the image formats, that
was
the way to go because the TIFF standard was likely to be around for a
long time and the various camera RAW formats probably not so much.
I don't know if you can convert them, but I think the DNG file will
encapsulate them.
