Here's a solution using the latter approach:
<xsl:for-each select="e">
<xsl:sort>
<xsl:for-each select="@*">
<xsl:sort select="name()"/>
<xsl:value-of select='name(), "=""", ., """ "' separator=""/>
</xsl:for-each>
</xsl:sort>
<xsl:copy-of select="."/>
</xsl:for-each>
Saxon 8.2 produces an error message that:
"A sequence of more than one item is not allowed as the @sort-key
attribute of xsl:sort".
OK: you need to wrap it like this:
<xsl:for-each select="e">
<xsl:sort>
<xsl:value-of>
<xsl:for-each select="@*">
<xsl:sort select="name()"/>
<xsl:value-of select='name(), "=""", ., """ "' separator=""/>
</xsl:for-each>
</xsl:value-of>
</xsl:sort>
<xsl:copy-of select="."/>
</xsl:for-each>
Besides this problem, does xsl:sort have a "sort-key" attribute? I
don't see it specified either in the latest WG draft or in the book.
Looks like the error message needs improving...
