Ah, that's right--it's called type-switching in XQuery, and it's something
I experimented with a year or two ago to see if I could really do
everything in XQuery that I do in XSLT. I love both, but I tend to use
XQuery for pulling and visualizing data from complex documents, and if I
need to represent a complete, complex file with just a few spot revisions,
XSLT really seems easier. It may be that I didn't find the right
documentation, though.

For type-switching, there's this:
https://en.wikibooks.org/wiki/XQuery/Typeswitch_Transformations

Admittedly, I know XSLT identity transformations better, and it's how I
teach my students to *start* their first XSLT because it's so very easy,
especially in XSLT 3.0: https://dh.newtfire.org/XSLTExercise1.html
I mean, seriously, what could be easier than xsl:mode
on-no-match="shallow-copy"/  , and then writing a couple of dedicated
template rules to change exactly what you need?

Cheers,
Elisa
