xsl模板未向主样式表提供正确的输出

Question

在allTemplate.xsl

<xsl:template match="myRadio">
    <xsl:variable name="radioName"/>
    <input type="radio" value = "F" name="{radioName}"/>
</xsl:template>

在main.xsl

<myRadio>
       <xsl:variable name="radioName" select="Fields/Radio/*" />        
</myRadio>

在生成的jsp页面中，这会创建<input type="radio" etc/>，其中radioName指向Fields/Radio/*上main.xsl的数据吗？
