Michael,
It might be simpler, but it's wrong. Firstly, the expression
attribute::*[name()] is rather pointless: it selects all attribute that
have a name, and all of them do.
I did not realize that because the testcases worked.
While namespace::*[name()] selects all
namespaces except the default namespace, so your test will fail for that
one.
You are absolutely right.
Your counting technique works on the nodes which is correct and not on
string values which is incorrect.
is-no-attribute-and-no-namespace():
"count(. | ../attribute::* | ../namespace::*) !=
count(../attribute::* | ../namespace::*)"
is-attribute(): "count(. | ../@*) = count(../@*)"
is-namespace(): "count(. | ../namespace::*) = count(../namespace::*)"
Thank you for that technique!
This is the diff for the tool, I updated dynxp.xsl [1] and xpath++ tool
[2].

Now correct output is generated for your sample:

$ xsltproc --stringparam xpathpar "//node()" dynxp.xsl i.xml

Subject: Re: [xsl] Q: XSLT 1.0 output of namespace
In getting to the solution below I found that
". = ../namespace::*[name()]"
as "is-namespace()" test is even simpler than Michael's
"count(. | ../@*) != count(../@*)".
Similarly ". = ../attribute::*[name()]" can be used as "is-attribute()".
It might be simpler, but it's wrong. Firstly, the expression
attribute::*[name()] is rather pointless: it selects all attribute that
have a name, and all of them do. While namespace::*[name()] selects all
namespaces except the default namespace, so your test will fail for that
one.
Secondly, it's quite possible to have an attribute and a namespace with
the same string-value, for example
<xs:schema xmlns:a="http://my.namespace/";
targetNamespace="http://my.namespace/";>
and in this case your test for a namespace and your test for an
attribute will both return true.
