Dear Scalable Vector Graphics Working Group,

  In http://www.w3.org/TR/2004/WD-SVG12-20041027/ the style of property
definitions is inconsistent with the CSS family of specifications, in
particular, the "Computed Value" field is missing from the property
tables. This field should be added to all properties to make it easier
to determine the computed value. It should for example be clear that the
computed value of url() values is the absolute URL but this is often
missed by implementers, for example,

  rect { fill: url(#myGradient) }

  <?xml-stylesheet type="text/css" href="001.css"?>
  <svg xmlns="http://www.w3.org/2000/svg" version="1.1">
  <defs><linearGradient id="myGradient"><stop offset="100%"
  stop-color="red" /></linearGradient></defs><rect fill="green"
  x="0" y="0" width="100" height="100" /></svg>

this must show a green rect, but e.g. the experimental implementations
in Mozilla Firefox and Adobe SVG Viewer 6 show a red rect. This should
thus be defined more clearly in the specification.
