[AstroPy] accessing raw astropy.io.votable.tree.Resource content

[Laurent Michel]

Hi Tom,

I’m a novice with the Astropy dev cycle, your help would be very appreciated.
I’ll first write an  ’new feature’ issue telling what I’m expecting.
After this we will be able to put our hands-on.

Laurent

However as I recall, I think it will require some changes to astropy.io.votable to save some of the content that it's not actively using.  That should be very doable and something we can work on together to make sure it does what we need.
