Hello ,

In this feedback
http://lists.w3.org/Archives/Public/public-cdf/2006Nov/0018.html

Oskari on behalf of Lasse points out that there is a copy paste error
such that frozen and static have identical descriptions after the
first sentence:

"An <object> element <param> child element with name="render" and
value="static" shall result in a static rendering. Links shall not be
activatable. Animations shall not play. Modifications made by script
shall update the rendering. The rendering shall also update, if the size
of the rendering area changes."

And

"An <object> element <param> child element with name="render" and
value="frozen" shall result in a one-time static rendering to a raster
image. Links shall not be activatable. Animations shall not play.
Modifications made by script shall update the rendering. The rendering
shall also update, if the size of the rendering area changes."

This conflicts with other parts of the spec; in particular it changes
the meaning of static as defined by SVG and it changes the meaning of
frozen (and contradicts one-time rendering) as defined in the rest of
WICD.

We will fix this by changing the descriptions as follows - static
*does* allow link traversal, according to the definition of static in
SVG which we reference, so we say so; frozen is one-shot so
repeat-shots (when the rendering area changes or when scripts run) are
out - they would otherwise require the original svg to be kept around
rather than tossed.

That gives us:

"An <object> element <param> child element with name="render" and
value="static" shall result in a static rendering. Links shall be
activatable. Animations shall not play. Modifications made by script
shall update the rendering. The rendering shall also update, if the size
of the rendering area changes."

And

"An <object> element <param> child element with name="render" and
value="frozen" shall result in a one-time static rendering to a raster
image. Links shall not be activatable. Animations shall not play.
Modifications made by script shall not update the rendering. The rendering
shall also not update, if the size of the rendering area changes.
The original SVG, once rendered, may be discarded by the client."

Hopefully it is now clear in what way frozen and static differ. Sorry
about the confusion this copy paste error caused.

Also, the first occurrences of "static" and "dynamic" will link to the
definitions of those terms in the SVG spec.

Please let us know if these corrections do not address your concerns.
