Bringing VOEvent v2.0 home to roost

[Mike Fitzpatrick]

Take the example in the PR doc describing <Reference>:

<Group type="MyFilterWithImage">
    <Reference uri="http://.../data/h.fits"
              type="http://.../data-models/#h-filter-image/>
</Group>

What do I actually get when I access the 'uri' (I know, a FITS file,
but how does the 'type' value tell me that)?  What if there wasn't
a ".fits" extension but some CGI query w/ an opaque identifier?

-Mike

P.S.  I'm not sure you realized your example was real or not...my
sister lives in Pennsylvania and Mike Fitzpatrick really is
her congressman 8-)
