If the attribute should always be present, you could just write:

<bachelor xsl:use-attribute-sets="{$who}"/>

You'd only need to use a conditional block and an attribute instruction in 
cases where the attribute might not exist.

You could also create structures like this one:

<bachelor xsl:use-attribute-sets="{if ($who='') then 'Oscar' else $who}"/>

That's potentially very powerful stuff.

I'd be in favor of a change like that if it won't cause problems in some 
other context.
