// is not the Union operator, but the Ancestry operator and starting a

| is the union operator.
<xsl:template match="//*"/> and <xsl:template match="*"/> are
effectively the same as you pointed out. Sometimes there are more than
one way of doing something, however
<xsl:apply-templates select="//*"/> and
<xsl:apply-templates select="*"/>
are very different in that "//*" will start at the document and select
all descendant elements, where "*" will start at the current element and
select only it's child elements.
