My understanding is that the code

 B  B  <xsl:variable name="x" as="element()">
 B  B  B  <a a1="a1" xmlns:a="http://a.uri/">
 B  B  B  B  <b b1="b1">
 B  B  B  B  B  <c/>
 B  B  B  B  B  <d/>
 B  B  B  B  </b>
 B  B  B  </a>

 B  B  </xsl:variable>

with theB exclude-result-prefixes="s" creates an "a" element and its
descendants (like the "c") element without any namespace node for the
s/http://s.com/ namespace.

Then the code

 B  B  B  <xsl:for-each select="$x//c">
 B  B  B  B  <ns>
 B  B  B  B  B  <xsl:value-of select="s:sort(namespace::*)" separator=","/>
 B  B  B  B  </ns>
 B  B  B  </xsl:for-each>

selects the namespace nodes of the "c" element, sorts and outputs them.

As, as I tried to explain above, the "c" element is created as a
descendant of the "a" element while exclude-result-prefixes="s" holds
and that way neither the "a" nor the "c" element node constructed have a
namespace node for s/http://s.com/, the selection of the namespace nodes
of the "c" element with namespace::* doesn't have any node for
"s/http://s.com/" and that way it is also not output, simply as the only
two namespace nodes the "c" element carries are the "a"/"http://a.uri/"
namespace and the XML namespace.
