What has been blindly copied is a text node.

(a) XML Schema wasn't around at the time XSLT was invented
(b) Even if it were, there is even today no way to declare an attribute as
containing an "XPath expression" (or a "list of namespace prefixes", to take
another example that XSLT uses).

A solution based on declaring those elements or attributes that contain
namespace prefixes in their content might have been workable if it had been
invented at the start. It now falls into the category of 20:20 hindsight.
