Default unexpected zero-length tokenize()

Dear all,

I have a series of files, some of which I need to tokenize, some of which not.

this is an example of both types

Code:
<div>
1
text 〈: in latere intuentibus sinistro〉 text 〈: in latere intuentibus dextro〉 text
</div>

2
<div>
text 〈: in latere intuentibus sinistro〉 text 
</div>

3
<div>
text 
</div>
the code I have done in my understanding should first look for the separating string 〈:***whichever***〉, but only use it to tokenize when it is there. if that is not present, just apply other templates.

Code:
<xsl:variable name="sections">
        <xsl:analyze-string select="." regex="(〈):(in latere intuentibus sinistro|in latere intuentibus dextro|in epystilio|in ipsa aedicula|in una linea|in parte aversa|in fgr.\s\w*\s*|in columna\s\w*\s*)(〉)">
            <xsl:matching-substring>
                <xsl:sequence select="."/> 
            </xsl:matching-substring>
        </xsl:analyze-string>
    </xsl:variable>
    
    <xsl:template name="div[@type='edition']">
        <xsl:copy>
            <xsl:apply-templates select="@*"/>
            <head>Text</head>
            <xsl:choose>
                <xsl:when test="contains(., $sections)">
                    <xsl:for-each select="tokenize(., $sections)">
                        <div n="{position()}" type="textpart">
   <ab>
...
                            </ab>
                        </div>
                    </xsl:for-each>
                </xsl:when>
                <xsl:otherwise>
                    <ab>
                        ...
                    </ab>
                </xsl:otherwise>
            </xsl:choose>
What happens is that with example 1 it returns the string, in example 2 actually performs the tokenize() and do the rest of the work nicely, in example 3 I get an Error (rightly) saying that tokenize is a zero length string... I understand why this second error comes, as the string is not there. I do not understand why it got to the point of evaluating that piece of xsl.

Thanks for any help.
