Order by attribute name

Using the IE5 syntax, I'd like to access the attributes of a tag in
alphabetic order. Could anyone ever manage a similar problem, I only could
order by the attributes' values using the code below:

<xsl:template match="*">
(...)
<xsl:apply-templates select="@*" order-by="+text()"/>
(...)  
</xsl:template>
