Removed: lib LICENSE.xerces_2_3_0.txt xerces_2_3_0.jar
Log:
1) Switch to Xerces 2.5.0 to resove performance issue with attributes
with large value fields (think data protocol images in xlink:href).
2) Few minor improvements to the handling of URL's in CSS.
3) Some documentation improvements/additions.

<answer>
<p>A common problem is that script contain the wrong DOM calls
to create elements or modify attributes. </p>
<p>SVG elements need to be
- created in the SVG namespace. For example, to create a <code><rect></code>
- element, you should use <code>document.createElementNS(svgNS, "rect")</code>,
- (where <code>svgNS</code> is equals to
<code>"http://www.w3.org/2000/svg";</code>),

+ <code><rect></code> element, you should use
+ <code>document.createElementNS(svgNS, "rect")</code>, (where
+ <code>svgNS</code> is equals to <code>"http://www.w3.org/2000/svg";</code>),
which appropriately creates the <code><rect></code> element in the
- SVG namespace. A call to <code>document.createElement("rect")</code> creates
- an element with the tag <code>rect</code> but which does not belong to the
- SVG namespace. As such, it is ignored by Batik.</p>
- <p>Most SVG attributes belong to what is called the 'per element type partition
- namespace' (see the <link href="http://www.w3.org/TR/REC-xml-names";>Namespaces

+ <p>Most SVG attributes belong to what is called the 'per element type
+ partition namespace' (see the
+ <link href="http://www.w3.org/TR/REC-xml-names";>Namespaces in
XML</link> specification). The appropriate way to set attributes on
an SVG element is a call to <code>setAttributeNS</code> with a namespace
- value of <code>null</code>, for example: <code>elt.setAttributeNS(null,
"width", "40")</code>.
- In the Batik SVG DOM implementation, you can also use a call to
<code>setAttribute</code> and
- you can write <code>elt.setAttribute("width", "40")</code>. However, it is
important
- to know that some implementations make a difference between
<code>setAttribute(x, y)</code>
- and <code>setAttributeNS(null, x, y)</code>, so it is a better practice to use
- <code>setAttributeNS</code> which is the only guaranteed interoperable way of
- setting attributes in a namespace aware DOM implementation.</p>

<p>Finally, for attributes which belong to a specific namespace, like the
the href attribute on the <code><image></code> element, you have to
- use the <code>setAttributeNS</code> method with the XLink namespace. For
example,
- assuming <code>img</code> references an <code><image></code> DOM
<code>Element</code>,
- you can modify the href as follows: <code>img.setAttributeNS(xlinkNS,
"xlink:href", "myImage.jpg")</code>
- where <code>xlinkNS</code> is equal to
<code>"http://www.w3.org/1999/xlink";</code></p>
