This is putting an xsl:use-attribute-sets on the result document
but attribute sets are a feature of XSLT.

it's same as xsl:version or version. On literal result elemenst you use
 xsl:use-attribute-sets 
on xsl elements (just xsl:element is relevant here) you use
   use-attribute-sets

The XSLT engine. attribue sets are just a different kind of variable.
You can use them if you are generating any sort of content, you wouldn't
expect an HTML browser to do anything with them.

You don't want to arrive there.

The FO renderer won't even see your attribute-set definition, which is
in the stylesheet. (Athough some won't complain about this attribute
from some foreign namespace)
