[xsl] recursive template

Hi,
         Iam having difficulty in getting this recursive call to a template
to work as expected.

I call once from main as follows:

<xsl:call-template name="study">
<xsl:with-param name="attrname" select="@name"/>
<xsl:with-param name="path" select="@type"/>
</xsl:call-template>


And I have the following in my 'study' template:

<xsl:template name="study">
<xsl:param name="attrname"/>
<xsl:param name="path"/>

<xsl:for-each select="child::*">

<!-- (A) -->
<xsl:message>name = <xsl:value-of select="@name"/></xsl:message>
<xsl:message>type = <xsl:value-of select="@type"/></xsl:message>

<!-- just a check to recurse selectively into some child nodes -->
<xsl:if test="not(substring-before(@type,':')='ps')">
 <!-- (B) -->
     <xsl:call-template name="study">
     <xsl:param name="attrname" select="@name"/>
     <xsl:param name="path" select="@type" />
     </xsl:call-template>
</xsl:if>
</xsl:for-each>

</xsl:template>


At (A), I would like to print out recursively the name and type attributes
of all the child nodes.
But the value remains constant, the same as I passed in from main.

I can however see that the correct value gets printed at (B).


Any suggestions are welcome.
