attribset23 questionable behavior

[Sc...@lotus.com]

Not sure I trust the attribset23 behavior.  It is different for XT, Saxon,
and Xalan.  Any opinions?

== xsl ==
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version

Thoughts?

I agree with the Xalan version of the output for attribset23.  This
exact example is shown in section 7.1.3 of XSLT 1.0 in the following
paragraph:

"XSLT processors may make use of the prefix of the QName specified in
the name attribute when selecting the prefix used for outputting the
created attribute as XML; however, they are not required to do so and,
if the prefix is xmlns, they must not do so. Thus, although it is not an
error to do:

<xsl:attribute name="xmlns:xsl"
namespace="whatever">http://www.w3.org/1999/XSL/Transform</xsl:attribute>

it will not result in a namespace declaration being output."

The Recommendation specifically says that this is not an error so the
Saxon behavior is wrong in my view.  Similary, XT outputs nonsense since
it defines no attributes other than namespace attributes which the
Recommendation specifically prohibits.  Xalan properly adds the
attribute with the local name "xsl" using a proper declaration for the
namespace URI.

With what part of the Xalan output do you disagree?
