These questions are helpful to me for writing the Internet Draft for 3.0.
In this case, the idea is that HSPACE and VSPACE provide whitespace margins.
So normally you would see a margin of HSPACE on either side of the figure.
If the figure is left aligned, then it seems reasonable to me to do so, and
only place the HSPACE on the right handside.

The VSPACE attribute specifies the leading preceding and following the figure.
I thing we should use the same conventions as for leading above and below
headers and paragraphs etc. That is, to set the vertical spacing to the
maximum of the leading following the previous element, and the leading
preceding the current one.
