XST - use the output from the call template as the return value

Question

Suppose I have a template foothat can output something specified by a parameter. Now I want to use this output as a parameter for my other template loop, so that I can cyclically output the output a certain number of times. I tried something along the way

    <xsl:call-template name="loop">
        <xsl:with-param name="times" select="someParam"/>
        <xsl:with-param name="output">
            <xsl:call-template name="foo">
                <xsl:with-param name="type" select="something"/>
            </xsl:call-template>
        </xsl:with-param>
    </xsl:call-template>

In other words, outputit should now contain the output of the call foo. Both loopand fooare operating normally regardless, but it seems that I can not put them. How am I supposed to do this? Thanks in advance.
