You can do that in XSLT 1.0 using modes and a node-set extension:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
    xmlns:ax="http://dyomedea.com" xmlns:exsl="http://exslt.org/common"
    extension-element-prefixes="exsl">
    <xsl:template match="*|@*">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="ax:repeat" name="ax:repeat">
        <xsl:param name="index">1</xsl:param>
        <xsl:variable name="rtf">
            <xsl:apply-templates mode="ax:repeat">
                <xsl:with-param name="index" select="$index"/>
            </xsl:apply-templates>
        </xsl:variable>
        <xsl:apply-templates select="exsl:node-set($rtf)/*"/>
        <xsl:if test="$index &lt; count(*/ax:items[1]/ax:item)">
            <xsl:call-template name="ax:repeat">
                <xsl:with-param name="index" select="$index + 1"/>
            </xsl:call-template>
        </xsl:if>
    </xsl:template>
    <xsl:template match="ax:items">
        <xsl:element name="{@element}">
            <xsl:apply-templates select="ax:item[1]"/>
        </xsl:element>
    </xsl:template>
    <xsl:template match="ax:item">
        <xsl:attribute name="src">
            <xsl:value-of select="@src"/>
        </xsl:attribute>
    </xsl:template>
    <xsl:template match="*|@*" mode="ax:repeat">
        <xsl:param name="index"/>
        <xsl:copy>
            <xsl:apply-templates select="@*|node()" mode="ax:repeat">
                <xsl:with-param name="index" select="$index"/>
            </xsl:apply-templates>
        </xsl:copy>
    </xsl:template>
    <xsl:template match="ax:items" mode="ax:repeat">
        <xsl:param name="index"/>
        <xsl:copy>
            <xsl:apply-templates select="@*|ax:item[$index]" mode="ax:repeat">
                <xsl:with-param name="index" select="$index"/>
            </xsl:apply-templates>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>
