Hi,

I could use this too, but I think we are mixing two many things together
here.  SVG is vector graphics on top of this should be a higher level
that then uses the vector graphics to make things like forms.  The
viewers are already too big and we need to start separating application
from graphics to create a smaller footprint.  If you want more then
there can be a separate module on top of SVG.

Mit freundlichen Grüßen/Regards

+1 grids

A simple example of where a grid would be useful is a simple form layout
with text labels and text entry boxes, like this:
             _____________
  E-mail:   |_____________|
             _____________
  Password: |_____________|

You want the text entry boxes (assume they are just rects for
simplicity) to have the same x coordinates.  This x coordinate should be
just to the right of the widest text label.  You also want each label to
be centered vertically with respect to its text field.

I can imagine grid cells working as flow regions.

  <grid vertical-align="middle">
    <gridRow>
      <gridCell>
        <flowPara>E-mail:</flowPara>
      </gridCell>
      <gridCell>
        <flowPara>
          <flowImage>
            <rect width="20em" height="1.5em"/>
          </flowPara>
        </flowLine>
      </gridCell>
    </gridRow>
    <gridRow>
      <gridCell>
        <flowPara>E-mail:</flowPara>
      </gridCell>
      <gridCell>
        <flowImage>
          <rect width="20em" height="1.5em"/>
        </flowPara>
      </gridCell>
    </gridRow>
  </grid>

(Maybe some of those flow* elements are redundant; I haven't looked at
them closely enough to know which ones are required and which ones can
directly contain content.)

I don't see any real impediment to using an HTML-style algorithm for
cell width determination.
