Re: [xsl] Namespace-alias using #default with no default namespace in scope

[David Carlisle <davidc@xxxxxxxxx>]

  Ah! Is a more recent version of the XSLT 2.0 spec available
  somewhere? I'm currently reading http://www.w3.org/TR/xslt20,
  which says: "W3C Candidate Recommendation 3 November 2005".


as it says at the top of (all) w3c working drafts the "undated" URI such
as http://www.w3.org/TR/xslt20 is always the most recent version (and
updated in place) when newer versions are published. The URI for a
particular draft is always of the form

http://www.w3.org/TR/2005/CR-xslt20-20051103/

which will always refer to the CR draft even if a later draft is
published.

It's only the bindings that are in scope on the xsl:namespace-alias
element that matter to namespace-alias (as far as resolving which
namespace #default refers to).

xslt2 is a more explict here. the rules imply (and the following note
makes explict) that the stylesheet-prefix is not used in the result.

   These rules achieve the effect that the element generated from the
   literal result element will have an in-scope namespace node that binds
   the result-prefix to the target namespace URI, provided that the
   namespace declaration associating this prefix with this URI is in scope
   for both the xsl:namespace-alias instruction and for the literal result
   element. Conversely, the stylesheet-prefix and the literal namespace URI
   will not normally appear in the result tree.
