Yes, your solution worked, and that is what I was moving toward; I

Glad to help.
I do have access to an XSLT 2.0 processor, and can probably modify
these stylesheets to use XSLT 2.0... For future reference, would you
mind explaining what the more graceful XSLT 2.0 solution would be?
Well in this case it wouldn't necessarily be a whole lot different.
Instead of testing "normalize-space($result)" you could test, for
example, "exists($result/fn)", which would be both more efficient for
the processor, and more robust (as well as more intelligible to the
maintenance programmer).
Or, instead, group them like so (into a single group):
<xsl:for-each-group select="$result/fn" group-by="true()">
<fn-group>
<xsl:sequence select="current-group()"/>
</fn-group>
</xsl:for-each-group>
Or you could change your entire approach, and instead of processing the
footnotes and then including your wrapper only conditionally (based on
testing to see if there were any results), you could simply post-process
your entire document to remove empty fn-group elements. This would be
conceptually cleaner, and it will also scale better to more complex cases.
Cheers,
Wendell
