Re: [xsl] XSLT 3.0: Questions about the Statically-known namespaces and default element/ type namespace for the evaluation context of the target expression of <xsl:evaluate>

So the default namespace in the stylesheet is not used,
and if there is no xpath-default-namespace attribute,
then there will be no default namespace for elements and types,
which means that "no prefix means no namespace".
The rules are exactly the same as for static XPath expressions in the 
stylesheet.

Thank you for making this clear.

Cheers,
Dimitre

The spec says:

        • if the namespace-context attribute is absent, then the in-scope 
namespaces of the xsl:evaluate instruction (with the exception of any binding 
for the default namespace) are used as the statically known namespaces for 
the target expression, and the value of the innermost 
[xsl:]xpath-default-namespace attribute, if any, is used as the default 
namespace for elements and types in the target expression.

So the default namespace in the stylesheet is not used, and if there is no 
xpath-default-namespace attribute, then there will be no default namespace

I believe that in case 2, the default-namespace binding of the
<xsl:evaluate> instruction should become the the default-namespace
binding in the evaluation context (the alternative is to ignore this
and nave no default-namespace binding for the evaluation case -- as
obviously should be done in case 1.)


No, this isn't what happens.

The rules for handling of the default namespace cause enormous problems for 
XSLT beginners, and I would love to change them if I could, but it's too late 
for that. And I think it's right that the rules for xsl:evaluate, in the 
absence of a namespace-context attribute, should be exactly the same as for 
static XPath expressions.
