On the contrary, I think it's quite clear.

  7.1.1 Literal Result Elements
  [...]
  The created element node will also have a copy of the namespace nodes
  that were present on the element node in the stylesheet tree with the
  exception of any namespace node whose string-value is the XSLT
  namespace URI (http://www.w3.org/1999/XSL/Transform), a namespace URI
  declared as an extension namespace (see [14.1 Using Extension
  Elements]), or a namespace URI designated as an excluded namespace.

Only namespace nodes are concerned.

The output tree must be a well-formed external entity. One may want files
like these:
doc1.xml
<!DOCTYPE doc [
<!ENTITY e SYSTEM "doc2.xml">
]>
<doc xmlns:pre="prefix-URI">&e;</doc>

doc2.xml
<pre:elt/>

The resulting doc is a well-formed XML document and conforms to the XML
Names spec:
<...strip the doctype...>
<doc xmlns:pre="prefix-URI"><pre:elt/></doc>

doc2.xml is a well-formed external entity even without namespace
declaration.

XSLProcessor: done

None of these XSLT processors strips element nodes, either they exclude the
namespace declaration (as I expected them to do) or they perform some
"namespace fixup" (adding back the removed namespace declaration, as the
dropped XSLT 1.1 WD said).
That's the way I interpret these results...
