here is an example XSL file that calls a named template then applies
templates later

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:template match="/">

  <xsl:call-template name="test"/>


</xsl:template>

<xsl:template name="test">
<xsl:apply-templates/>
</xsl:template>

</xsl:stylesheet>

i think that u are saying that templates that call themselves infinately are
wrong, as the one listed below ( which will not work ! though some
processors will automagically iterate once  )

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:call-template name="test"/>
</xsl:template>
<xsl:template name="test">
 <xsl:call-template name="test"/>
</xsl:template>

</xsl:stylesheet>

sometimes people confuse recursion with circular references, the above is a
circular reference.

for example x=x+1 could be thought of as recursive, but in actuality it goes
on 'forever'.... which means that the function never bottoms out...
recursion always bottoms out ( c'mon u GEB readers.... ).

in some logic circles ( ah the keyword ) the x=x+1 is a circular reference,
whereas infinity is defined as a symmetrical circular existential being from
the planet grok.

to answer your question, yes u can use apply-templates ( if u use the select
condition be aware of what is the current node context ), and if u are using
a call-template make sure its not a runaway train.
