In this case, no since it's (row,col) not (row,cell).

This is interesting, vertical/horizontal or horizontal/vertical definition.

It should contain all of %SVG.g.content;
I just couldn't compile it properly.


Do you prefer a free ad hoc definition for grids?

<grid>
  <grid-rows><grid-col></grid-col></grid-rows>
</grid>

OR

<grid>
  <grid-cols><grid-row></grid-row></grid-cols>
</grid>

OR

<grid>
  <grid-cell row='1' col='2'></grid-cell>
</grid>
