+1 for consistency. This said, I don't see a reference to the term "deep
copy" in any of:
- XPath 3.1 [1]
- XQuery 3.1 [2]
"XPath and XQuery Functions and Operators 3.1" [3] uses the term twice but
without defining it.
The closest I find is one of the default templates in XSLT 3.0 [4], which
says:
The effect of processing a tree using a mode that specifies
on-no-match="deep-copy" is that an unmatched element in the source tree is
copied unchanged to the output, together with its entire subtree.
I think that we do mean "deep copy" in the sense of "copied unchanged". Per
the spec, the target has to be an element node and it would not make sense
to NOT copy the attributes of that element.
