Hello,

does the stylus XQuery processor implement the copy-namespaces mode strictly according to the W3C recommendation? It seems to me - not quite, at least as far as document constructors are concerned. The query

declare copy-namespaces no-preserve, inherit;
document {
<a xmlns:ns1="example.ns1">
<ns1:b>bla1</ns1:b>
<ns1:b>bla2</ns1:b>
</a>
}

should produce a result in which <a> does not have any in-scope namespaces (thanks to "no-preserve"). However, I get this:

<a xmlns:ns1="example.ns1">
<ns1:b>bla1</ns1:b>
<ns1:b>bla2</ns1:b>
</a>

Or is this to be explained by a serialization process which strives to place namespace declaration attributes intelligently, though not warranted by the actual in-scope namespaces?

The example looks strained, but I want to know exactly what the processor does, rather than guess.

Thank you for information -

Hi Hans-Juergen,
it looks you have found a bug in the XQuery processor: the
construction of document nodes ignores the copy-namespace directive.
You will get the same results of Saxon if you wrap that node in
another element, e.g.

declare copy-namespaces no-preserve, inherit;
document {
<root><a xmlns:ns1="example.ns1">
<ns1:b>bla1</ns1:b>
<ns1:b>bla2</ns1:b>
</a></root>
}

The bug will be fixed in the next update of Stylus.

Thanks for reporting this,
Alberto

Hello Alberto,

thank you very much for the prompt information!

Unfortunately, I did not quite understand your remark about Saxon, related to the example you gave. At any rate, trying out your example with Saxon (as well as with the built-in processor), I got the correct results, or so it seemed to me. If you wanted to point out something else, it would be kind to let me know.

Kind regards -
Hans-Juergen

Hi Hans-Juergen,
I'm sorry my remark was not clear; I was trying to say that both processors (Stylus and Saxon) return the same result if the <a> element is a children of another element, instead of a children of a document node.
Alternatively, it means that Stylus does support the copy-namespace property, but there was a bug when document nodes were involved.

Hope this helps,
Alberto
