Hi John,

Thanks for responding! I have a few clarifying questions mainly around 
Attr, because I don't quite understand what values are stored.

When you say adding `vertical-align` to attributes should be okay, how do 
you mean? Would it be more appropriate to store it in the XML format that 
docx uses to denote vertical alignment?

As well, I think I was a little thrown off by some of the black box testing 
we did on the HTML reader. When we ran `pandoc -f html -t native` on the 
following HTML:

<table>
   <tbody>
      <tr>
         <td style="background-color: green>green background</td>
      </tr>
   </tbody>
</table>

We received the following output:

[ Table
    ( "" , [] , [] )
    (Caption Nothing [])
    [ ( AlignDefault , ColWidthDefault ) ]
    (TableHead ( "" , [] , [] ) [])
    [ TableBody
        ( "" , [] , [] )
        (RowHeadColumns 0)
        []
        [ Row
            ( "" , [] , [] )
            [ Cell
                ( "" , [] , [ ( "style" , "background-color: green" ) ] )
                AlignDefault
                (RowSpan 1)
                (ColSpan 1)
                [ Plain [ Str "green" , Space , Str "background" ] ]
            ]
        ]
    ]
    (TableFoot ( "" , [] , [] ) [])
]

Seeing that the style was preserved led us to believe that it would be 
appropriate to store some styling in the AST. Is the problem with our 
proposed solution that we would be storing information that would be 
specific to HTML? Is there maybe a more generic language that would be more 
appropriate to store that information in?  

Thanks,

Noah
