SliderVertical widget causing parse error in an XHTML document

[guest]

I want to create a vertical slider in my JSF application. However, when I create this widget I get the following error (since I am using XHTML as my document)

DEBUG: dojo.widget.Parse: error: [Exception... "An invalid or illegal string was specified" code: "12" nsresult: "0x8053000c (NS_ERROR_DOM_SYNTAX_ERR)" location: "​http://localhost:8080/dojotrial/js/dojo/dojo.js Line: 286"]

I find that when I create the same slider in an HTML document, it works perfectly fine:

<div id="verticalSlider" dojoType="SliderVertical?"

initialValue="5" snapValues="9" maximum="9" minimum="1" clickSelect="true" buttonStyle="width:28px;height:16px;" backgroundStyle="padding:8px 8px 8px 8px;border:1px solid red;background-color:yellow;" progressBackgroundSrc="js/dojo/src/widget/templates/images/slider-bg-progress-vert.gif" handleStyle="left:2px;top:-1px;" handleSrc="js/dojo/src/widget/templates/images/slider-button-vert.png" flip="true"

</div>

However, the same in my XHTML file fails.

(In [9313]) Fixes #2813, #1878, #2787. Created new 0.9 sider. Still needs css and a11y tweaking and tick mark support.
