Right, "clone" == "deep copy" ;)

I am now a little puzzled that there is no simple formal definition in any
of the XML specs, although to be fair, XSLT doesn't work via mutation but
by producing new trees, while here we have mutation.

The DOM has a `cloneNode(deep)` function. [1] However, reading it doesn't

The actual logic is simple: all node properties must be preserved in a deep
