No you can't, variables are immutable in XSLT once bound.

  <xsl:output method="text"/>
  <xsl:strip-space elements="*"/>
  <xsl:template match="ROOM" name="counter">
    <xsl:param name="i" select="1"/>
    <xsl:if test="$i &lt;= @quantity">
      <xsl:value-of select="$i"/>
      <xsl:if test="not(not(following-sibling::ROOM) and $i = @quantity)">,</xsl:if>
      <xsl:call-template name="counter">
        <xsl:with-param name="i" select="$i + 1"/>
      </xsl:call-template>
    </xsl:if>
  </xsl:template>
