If the data and display elements that you want to associate are
already associated (as they are in this structure) then why not just
use that association?

For example, rather than using the lookup template at all, you could
just do:

  <select name="test">
    <xsl:for-each select="/test/nodes/level2">
      <xsl:sort select="display" />
      <option id="{data}" value="{data}">
        <xsl:value-of select="concat(data, '-', display)" />

I guess that you're using the lookup template so that you can create
other select elements in the same kind of way elsewhere. Making the
lookup template absolutely generic will make it comparatively
inefficient, so before going to that extreme, perhaps you could
describe the variety of situations in which you want to use the lookup
template? For example, are the display nodes and associated data nodes
always siblings of each other, nested under some other node?
