I agree that this is a requirement.

When an SVG drawing/fragment is part of a parent's XML/CSS page, you define
the box for the SVG drawing/fragment using CSS positioning. Thus, the box
for the SVG drawing can be defined just like images (i.e., percentages or
absolute width/height). In the following example, the <g> element is an SVG
fragment which is given a width of 10% of the width of its containing block
(i.e., the frame) and a height of 300 pixels:

<?xml version="1.0"?>
<MyXMLPage xmlns="...">
   <!-- Now include an SVG fragment -->
   <g xmlns="...svg..."
         style="width: 10% height: 300px">
         <!-- Contents of the SVG fragment ... -->

In the WG, we are also talking about adding a capability such that SVG
drawings can be self-sizing (i.e., the contents of the drawing determine
how how to compute content-width and content-height): images can be
self-sizing, so it seems very graphics should, also.

Once you have defined your box for the SVG drawing/fragment, then you get
to control whether the SVG drawing/fragment should scale to fit the box, or
whether it should stay a particular size no matter what. The main way that
you get an SVG drawing/fragment to scale to fit is the 'transform:
fit(...)' property (see section 8.7 in the current draft spec).
