Is it meaningful to take the intersection of a sequence of element nodes
and a sequence attribute nodes, like this:

<xsl:variable
  name="intersection"
  select="a/b intersect c/@d"/>

The intent is to match their string values, so would something like this
be better:

<xsl:variable
  name="intersection"
  select="a/b/text() intersect c/@d/text()"/>

Thanks!
