Re: what are node set fragments and why are they ruining my life?

well I said that this extension could be used to get back a node set,
but probably (if I understood quite what you want to do, which I don't)
you wouldn't need this as you could avoid building a result tree
fragment too early (which appears to be your problem)

That's to be expected.

well node-set isn't standard of course, but probably it is putting a
root node on it, so in that case you probaly want
  "xt:node-set($members)/*"

so why not just do that?

If you have

<xsl:template name="god-awful">
  <xsl:apply-templates
     select="foo|a/b[@xx]/c[@aa and @dd='this']|aa[dd[cc]]"/>
</xsl:template>


then you can just use

<xsl:call-template name="god-awful"/>

whenever you want to do an apply based on that select expression in some
other template.
