That should surely be:

<xsl:variable name="vKeyword" select="'notification'"/>

This means that Class/@classname contains more than one attribute, which
means that the context node has more than one child called Class.

What to do about it? This depends on whether you want to check if *any* of
these attributes contain the keyword, or if *all* of them contain the
keyword. The 1.0 code checks if the *first* one of the attributes contains
the keyword.
