Assuming 'foo' elements can have a 'bar' and a 'baz' attribute and you want
to process them sorted on @bar if present, otherwise on @baz then the
following XSLT 2.0
<xsl:apply-templates select="foo">
<xsl:sort select="(@bar, @baz)[1]"/>
</xsl:apply-templates>
does that nicely I think.
How would you translate that to XSLT 1.0? I can only think of a temporary
tree (created with a node-set extension function) where you create a new
attribute merging the two attributes first, then process the temporary tree
sorted on the new attribute.
What's wrong with:
(@bar | @baz)[1]
?
