No (in XSLT 1.0), but you can use the xsl:attribute instruction and perform 
a for-each inside it.

<a>
  <xsl:attribute name="href">
    <xsl:text>page.jsp</xsl:text>
    <xsl:for-each select="...">
      <xsl:choose>
        <xsl:when test="position() = 1">?</xsl:when>
        <xsl:otherwise>&amp;</xsl:otherwise>
      </xsl:choose>

Cheers,
Wendell
