apply-templates vs. call-template problem

Hi,

I'm using xsltproc on freebsd. I've encountered a problem that
I think is because I don't understand xsl/xml namespaces?  Anyway, I
got my xsl stylesheet to work below using the template:

<xsl:stylesheet version="1.0"
       xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
       xmlns:str="http://exslt.org/strings"
       xmlns:set="http://exslt.org/sets"
       xmlns:regexp="http://exslt.org/regular-expressions"
       xmlns:exslt="http://exslt.org/common"
       xsl:extension-element-prefixes="str set regexp exslt"
       >
<xsl:output method="text" indent="no"/>

<xsl:template match="/schema">
                               <xsl:call-template name="create-groups"
select="."/>
                               <xsl:call-template
name="create-partitions" select="."/>
                               <xsl:apply-templates select="tables/table"/>
                               <xsl:call-template
name="table-permissions" select="."/>
                               <xsl:call-template name="table-indices"
select="."/>
                              <xsl:call-template name="oid-indices"
select="$top/schema"/>
</xsl:template>

I then decided it would be nice to just call each template
if a command line flag was specified, but, I can't get it to work for
the call-template variety.  The apply-templates seems to work if
I create an anchor $top variable to 'reselect'....

<xsl:stylesheet version="1.0"
       xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
       xmlns:str="http://exslt.org/strings"
       xmlns:set="http://exslt.org/sets"
       xmlns:regexp="http://exslt.org/regular-expressions"
       xmlns:exslt="http://exslt.org/common"
       xsl:extension-element-prefixes="str set regexp exslt"
       >
<xsl:param name="actions"
select="string('groups,partitions,tables,tablepermissions,tableindices,oidindices')"/>
<xsl:output method="text" indent="no"/>

<xsl:template match="/schema">
       <xsl:variable name="top" select="."/>
       <xsl:for-each select="str:tokenize($actions, ',')">
               <xsl:choose>
                       <xsl:when test=". = 'groups'">
                               <xsl:text>got groups&#xa;</xsl:text>
                               <xsl:call-template name="create-groups"
select="."/>
                       </xsl:when>
                       <xsl:when test=". = 'partitions'">
                               <xsl:text>got partitions&#xa;</xsl:text>
                               <xsl:call-template
name="create-partitions" select="$top"/>
                       </xsl:when>
                       <xsl:when test=". = 'tables'">
                               <xsl:text>got tables&#xa;</xsl:text>
                               <xsl:apply-templates
select="$top/tables/table" mode='tables'/>
                       </xsl:when>
                       <xsl:when test=". = 'tablepermissions'">
                               <xsl:text>got tablepermissions&#xa;</xsl:text>
                               <xsl:call-template
name="table-permissions" select="."/>
                       </xsl:when>
                       <xsl:when test=". = 'tableindices'">
                               <xsl:text>got tableindices&#xa;</xsl:text>
                               <xsl:call-template name="table-indices"
select="."/>
                       </xsl:when>
                       <xsl:when test=". = 'oidindices'">
                               <xsl:text>got oidindices&#xa;</xsl:text>
                               <xsl:apply-templates
select="$top/tables/table" mode='oid-indices'/>
<!--                            <xsl:call-template name="oid-indices"
select="$top/schema"/> -->
                       </xsl:when>
                       <xsl:otherwise>
                               <xsl:message terminate="yes">
UNKNOWN command line argument: <xsl:value-of select="."/>
                               </xsl:message>
                       </xsl:otherwise>
               </xsl:choose>
       </xsl:for-each>

</xsl:template>

In this example just the 'apply-templates' calls work.  The 'call-template'
fires, but I can't seem to 'select' the /schema tree.

In both cases my xml data looks like:

<schema name="ad_schema" database="ad_voip">
<tables>
  <table name="at_address" perm="superuser">
    <comments>
      Address
      This is an address record.
      It is normally included in other record's views.
    </comments>
    <fields>
<field is_nullable="1" data_type="text" name="ac_b" >
        <comments>
          Brand ID
          This address belongs to this brand.
        </comments>
      </field>

...



Thank you,
