Confirmed errors:


(8)  Example 1-2;
To get the SVG example to work in Firefox, I had to add the SVG namespace to the svg element: xmlns="http://www.w3.org/2000/svg"
AUTHOR NOTE: Correct, but not detectable when book was written, because Firefox wasn't available then.


(29) just after the bulleted list and before Example 3-3, add:

  It is also possible to use one of the color keywords listed in section
  4.2 of the SVG specification at
  http://www.w3.org/TR/SVG/types.html#ColorKeywords,
  or one of the CSS 2 system color keywords as listed at
  http://www.w3.org/TR/REC-CSS2/ui.html#system-colors
  
  
(39) Example 3-13 (code) lacks stroke color values so horizontal lines don't show.
Corrected code:

<line x1="10" y1="15" x2="50" y2="15"
    style="stroke: black; stroke-linecap: butt; stroke-width: 15;"/>

<line x1="10" y1="45" x2="50" y2="45"
    style="stroke: black; stroke-linecap: round; stroke-width: 15;"/>

<line x1="10" y1="75" x2="50" y2="75"
    style="stroke: black; stroke-linecap: square; stroke-width: 15;"/>

<!-- guide lines -->
<line x1="10" y1="0" x2="10" y2="100" style="stroke: #999;"/>
<line x1="50" y1="0" x2="50" y2="100" style="stroke: #999;"/>


  
{42}  last line before 'Specifying Colors' section;
<line x1="1cm" y1="30" width="50" height="10pt"/>
should be
<line x1="1cm" y1="30" x2="50" y2="10pt"/>

(45) Remove the angle brackets around the word "style" in the second
sentence under the subhead "Inline Styles."


(64)  Top and Figure 5-8;
The first and second code fragments both give height="20" and width="15" with uniform
scaling on each of the axes, yet Figure 5-8 shows a rectangle wider than it is high.

the height and width should be
height="15" and width="20"
for both of those code fragments


{84} The comments in the program at the bottom of the page should
begin with these lines:

   # Convert an elliptical arc parameterized for SVG to an
   # elliptical arc based around a central point.
   
   
(85)  2nd line in convert_from_svg function;
The $phi in the second "my" line should be $pi. 


(97)  last line;
markerWidth="6" and markerHeight="10"
should be:
markerWidth="4" and markerHeight="8"
   

(165)  2nd last paragraph;
change flood-fill-color to flood-color
change flood-fill-opacity to flood-opacity   


(181)  <feFlood>;
change "flood-fill-color" to "flood-color"
change "flood-fill-opacity" to "flood-opacity"


{196}  1st line in Example 11-18;
The MIME type text/ecmascript is obsolete and should be application/ecmascript according to RFC 4329.


[196]  1st line in enlarge_circle() and shrink_circle() functions;
The code "var circle = evt.getTarget();" does not work in Firefox or Opera. The code "var circle = evt.target;" works


[198]  1st line in setScale() function;
The line "obj = svgDocument.getElementById..." does not work.
The fix is to put this in the init() function:

   if (window.svgDocument == null )
   {
      svgDocument = evt.target.ownerDocument;
   }


{205}  1st line in Interacting with an HTML page section;
The <embed> element is nonstandard. The standard <object> element should be used instead.
AUTHOR NOTE: Since the time of the book's writing, <object> has become the preferred method of including an SVG graphic in a web page.


(210) top of page:

   Eliminate sentence "The numbered callouts in the example
   are in conceptual order, not text order."


{218} Under "Using Perl to Convert Custom Data to SVG"

"One of these is the proprietary format developed by Earth Science Resources, Inc. for
use by their ARC/INFO Geographic Information System"

Should be:

"One of these is the proprietary format developed by Environmental Systems 
Research Institute for use by their ArcInfo Geographic Information System."


{228} Change all occurrences of "UTF8" to "UTF-8".


{311}  2nd to last paragaph;
"Cross product" is a fancy way of saying "add up the productes of the coresponding entries in a row and column"...
should be:
"Dot  product" is a fancy way of saying "add up the productes of the coresponding entries in a row and column"...

All three occurrences of "cross product" should be "dot product"


(322) title for Example F-1.
XHTML and SVG in one cocument
should read:
XHTML and SVG in one document
