xsl:attribute
Creates an attribute on the nearest enclosing result element.
<xsl:attribute name="class" select="'highlight'"/>Useful when an attribute name or value depends on runtime values, or when an attribute should only be added conditionally. The instruction must run before any non-attribute content is written to the parent element.
The value can be supplied via the select attribute or via a sequence constructor body. The name and namespace attributes are attribute value templates.
