Re:  Global namespace prefixes (Corrected Examples)
Oddly, When I run the stylesheet (below), against the data (below) I get:

<?xml version="1.0" encoding="UTF-8"?>
<output xmlns:dap="http://xml.opendap.org/ns/DAP/3.2#" xmlns:ns0="http://base.document " ns0:ns="http://base.document">
<base:Conventions xmlns:base="http://base.document">CF-1.0</ base:Conventions>
<base:logname xmlns:base="http://base.document">olson</base:logname>
<base:host xmlns:base="http://base.document">bb0001en</base:host>

It just ignores the prefix when the attribute is added to the output element.

Here's a different approach. I don't know if the requirements allow it, but basically the idea is to create a dummy attribute in the new namespace on the document element, where the namespace will then be declared, leaving it in scope lower down, and thereby relieving the need to declare it for each of the lower-level elements.


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

 <xsl:output method='xml' version='1.0' encoding='UTF-8'

<xsl:variable name="ns" select="/dap:Dataset/@base"/>

<xsl:variable name="prefix" select="'base'"/>

  <xsl:template match="dap:Dataset" >
         <xsl:attribute name="{$prefix}:ns" namespace="{$ns}">
           <xsl:value-of select="$ns"/>
           <xsl:apply-templates />

  <xsl:template match="dap:Attribute" >
      <xsl:element name="{$prefix}:{@name}" namespace="{$ns}">
        <xsl:value-of select="." />


On the data

<Dataset xmlns="http://xml.opendap.org/ns/DAP/3.2#" base="http://base.document ">
<Attribute name="Conventions" >CF-1.0</Attribute>
<Attribute name="logname" >olson</Attribute>
<Attribute name="host" >bb0001en</Attribute>

using Xalan, I get

<output xmlns:dap="http://xml.opendap.org/ns/DAP/3.2#" xmlns:base="http://base.document " base:ns="http://base.document">

Yes, there's a bit of scat there; I don't know if that presents a problem. But no XSLT extension, and hence no extension namespace, is required.
