Indeed Liam, file:write() is one of my go-tos.  My main one, in fact. 
Ought to have mentioned that in my original message.
Good point re XSLT 4 and aggregating modes within the tag itself.
And as regards Renton, that's very cool. :)
Thanks,

You can also use the exslt file:write() function to write it out, which
does not have that limitation.

  One way is to isolate templates involving the same mode within their
  own file, 

in XSLT 4 as proposed, you can put all templates for a given mode inside
the xsl:mode element (although i am not sure you can enforce that,
unfortunately, but it would be relatively easy to check automatically
that you had done this)
The first joint XQuery and XSL meeting i went to as W3C staff contact for
XQuery was in Renton by the way.
