A question about the XSLT recommendation..
If you add the following to your XSLT stylesheet:
<test xmlns="http://test";>
<xsl:attribute name="test"/>
</test>
What namespace should that attribute receive? Should the result be:
<test xmlns="http://test"; test=""/>
Yes.
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."
That means: you take the prefix and look it up in the set of in-scope
namespace declarations. If there is no prefix, the attribute ends up in no
namespace.
Perhaps it doesn't say this in pedantic detail. However, the process of
expanding a lexical QName is fairly well understood: when there is no
prefix, you either use the default namespace, or you end up with a name that
is in no namespace; this text makes it clear that you don't use the default
namespace, therefore the only option left is to end up in no namespace.
