Internet Explorer - Ver 8 and previous: Setting a class attribute value gives '[object]' instead of the real string value

Description

This only affects IE versions 8 and previous:

Dynamically setting the value of a class to any string value results in the '[object]' value being assigned instead of the real string value. For example:

<xsl:tempate match="item">
<li class="{'open'}">
   <xsl:value-of select="."/>
</li>
</xsl:template>

Will result in the HTML element: <li class="[object]">First Item</li>

Cause: IE8 and previous versions treat the class attribute as a property of an element called 'className'. Saxon-CE manages this when reading attributes, but when writing, it was only setting the class attribute value. Setting the 'className' property resolves the issue.

Further investigation showed that the align@, @colSpan@, @id@, @rowSpan@, @title and width attributes for Internet Explorer up to and including version 8 are similarly affected - with '[object]' being assigned as the attribute value rather than the literal string value supplied. This has been fixed for the next Saxon-CE release.

Summary list of known affected attributes so far:

align

class

colSpan

id

rowSpan

title

width

Given the number of possible attributes affected in pre-IE9 browsers: a more reliable and performant solution than a lookup-list will probably be to test for the existence (ie not "undefined") of a matching element property name for the attribute and update the property if found...
