[xsl] recursion

Problem:  I have an XML file that has notes mixed up with comments.  I want to 
move the notes from current location to Notes element.  There could be 0 to 10 
notes.
Solution:  I will first copy notes found in   
span[@class='x']    
from current location to Notes.  With a second XSLT I will delete the unwanted 
ones.

        <xsl:variable name="notes" 
select="ancestor::Lexicon_Entry//LEXMeanings[1]//LEXSense[@LanguageCode='pt']//span[@class='x']"/>

Recursive code XSLT 2.0:
    <xsl:template name="get_note">
        <xsl:param name="notes" select="."/>
        <xsl:param name="number" ><xsl:value-of select="."/></xsl:param>
        number /<xsl:value-of select="$number"/>/       
        notes[number] /<xsl:value-of select="$notes[$number]"/>/       
        notes /<xsl:value-of select="$notes"/>/       
        <xsl:choose>
            <xsl:when test="exists($notes[$number])">
                <xsl:element name="note">    
                <xsl:attribute name="Caller"><xsl:value-of 
select="$number"/></xsl:attribute>
                <xsl:attribute name="LanguageCode">pt</xsl:attribute>
                <xsl:element name="Content">
                    <xsl:copy-of select="$notes[$number]"/>
                </xsl:element>
            </xsl:element>
                <xsl:call-template name="get_note">
                    <xsl:with-param name="notes" select="$notes"/>
                    <xsl:with-param name="number"><xsl:value-of select="$number 
+ 1"/></xsl:with-param>
                </xsl:call-template>
            </xsl:when>
            <xsl:otherwise>
            zzzzzzzz    <!-- end -->    
            </xsl:otherwise>
        </xsl:choose>
    </xsl:template>

This works fine for 0 or 1 notes but when 2 or more are found it goes into an 
endless loop.
Here is output with debugging code showing values
    <Note Caller="1" LanguageCode="en">
        <References/>
        <Content>There are no doubt certain subtle differences of meaning in 
these terms, especially in their connotations, but it is not possible to 
specify the difference on the basis of existing contexts.</Content>
      </Note>
    <Note Caller="1" LanguageCode="pt">
              <Content>
              <span class="x">2 Com certeza existem sutis diferenças de 
significado entre esses termos, especialmente em termos conotativos, mas não é 
possível determinar isso com base nos contextos disponíveis. 
</span></Content></Note>

        
 <note Caller="2" LanguageCode="pt"><Content><span class="x">3 Em Mt 5.21, 
<span lang="gk">κρίσις</span> se refere, provavelmente, a um tribunal local. 
</span></Content></note>
    

        number /3/       
        notes[number] /2 Com certeza existem sutis diferenças de significado 
entre esses termos, especialmente em termos conotativos, mas não é possível 
determinar isso com base nos contextos disponíveis.  3 Em Mt 5.21, κρίσις se 
refere, provavelmente, a um tribunal local. /       
        notes /2 Com certeza existem sutis diferenças de significado entre 
esses termos, especialmente em termos conotativos, mas não é possível 
determinar isso com base nos contextos disponíveis.  3 Em Mt 5.21, κρίσις se 
refere, provavelmente, a um tribunal local. /       
        
so when $number is 3, $notes[$number] is the same as $notes but $notes[3] is 
the empty set.  
I have verified that $number is actually an integer.  In this example there are 
two notes. The first note starts with 2 Com ... and the second note starts with 
3 Em ...

This puts me in an endless loop as it always finds something in $notes[$number]
