<xsl:copy-of> does indeed produce a copy with no additions. But the
validate function, which is typically invoked implicitly when building
the initial source tree, or explicitly when you write something like
<xsl:element validate="strict">, causes a modified copy, in which (a)
elements and attributes are annotated with their types, and (b) defaults
are expanded.
