Need dynamic metrics in SVG 1.2 / 2.0

Requirement suggestion:

It is often important to be able to specify
layout in terms of dimensions not easily
determined when the SVG is authored (generated).

Two examples:

1) math typesetting, where exact dimensions of
rendered variable names are needed to accurately place
them in an equation.

2) to allow an SVG layout to respond dynamically to
animation, like keeping a circle properly circumscribing
an animated path.

If order of rendering can be guaranteed, it should be
possible to allow one SVG element to make reference to
dynamic attributes of one previously rendered, at least its
position, bounding-box and baseline.
