A question about the XSLT recommendation..

I think you'll find the answer in the Namespaces in XML recommendation.

If you add the following to your XSLT stylesheet:
        <test xmlns="http://test">
                <xsl:attribute name="test"/>

What namespace should that attribute receive?

Namespaces in XML states that attributes without prefixes are in no namespace, not in the default namespace:


Should the result be:
        <test xmlns="http://test" test=""/>

Yes ... because the element is in the default namespace and the attribute is in no namespace.

The XSLT 2.0 recommendation states:
        "If the namespace attribute is not present, then the lexical Qname
         is expanded into an expanded-QName using the namespace declarations
         in effect for the xsl:attribute element, not including any default
         namespace declaration."

Makes sense since unprefixed attributes are in no namespace.

The xsl:attribute has no namespace attribute, and the lexical Qname contains no prefix. But since de default namespace declaration should not be included in resolving/expanding the Qname, I would expect the latter result should appear.

Not when you take into consideration that unprefixed attributes are in no namespace.

 However, the latter is not valid according to:
        (http://www.w3.org/TR/REC-xml-names/#ns-decl, 2nd paragraph or so)

..nor does any of the common implementations give that result, the all return the first..

As they should.

Am I misinterpreting the XSLT recommendation?

No, you are unaware of the constraints of the namespaces recommendation.

I hope this helps.
