problem accessing parameters in templates without an <

In Xalan 1.2, i could pass a parameter from one template to another and then
call a 3rd template with
<xsl:with-param> without having another <xsl:param> in the 2nd template. it
used to work in Xalan 1.2. but in Xalan 2.0, i have to first define an
<xsl:param> and then pass it down. Is this a feature or a bug ? I know the
XSLT spec
says, parameters are ignored when there is no explcit <xsl:param> in a
template. but i liked the default feature in
previous version of Xalan.

eg

this works in Xalan 1.2.2 but not in Xalan 2.0

<xsl:template name="company" mode="process">
<xsl:param name="testVar" select="1"/>
<xsl:apply-templates select="person" mode="process">
	<xsl:with-param name="testVar" select="$testVar"/>
</xsl:apply-templates>
</xsl:template>

<xsl:template name="person" mode="process">
	<xsl:apply-templates select="address" mode="process">
		<xsl:with-param name="testVar" select="$testVar"/>
	</xsl:apply-templates>
</xsl:template>

<xsl:template name="address" mode="process">
<xsl:value-of select="$testVar"/>
</xsl:template>

to make the above code work in Xalan 2.0 I had to do this

<xsl:template name="person" mode="process">
<xsl:param name="testVar" select="$testVar"/>
	<xsl:apply-templates select="address" mode="process">
		<xsl:with-param name="testVar" select="$testVar"/>
	</xsl:apply-templates>
</xsl:template>

<xsl:template name="address" mode="process">
<xsl:param name="testVar" select="$testVar"/>
<xsl:value-of select="$testVar"/>
</xsl:template>
