xsl:for-each loop generates wrong namespace declarations

           Summary: xsl:for-each loop generates wrong namespace declarations
           Product: XalanJ2
           Version: 2.4
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Major
          Priority: Other
         Component: org.apache.xalan
        AssignedTo: xalan-dev@xml.apache.org
        ReportedBy: mex02@erv.de


As the following example shows, xalan produces different output
depending on how the inner element of the for-each is declared.
If the namespace is evaluated by a "curlybracket-expression"
an unnecessary (and wrong) null namespace is generated.

Example.xml:
<?xml version="1.0"?>
<root>
  <myNameSpace>http://test.dynamic.url</myNameSpace>
  <list>
    <listelem>one</listelem>
    <listelem>two</listelem>
  </list>
</root>


Example.xsl:
<?xml version="1.0"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:template match="/">
  <xsl:element name="newRoot" namespace="{normalize-space(root/myNameSpace)}">
    <xsl:element name="elementOk"
namespace="{normalize-space(root/myNameSpace)}">foo</xsl:element>
    <xsl:for-each select="root/list/listelem">
      <xsl:element name="elementError"
namespace="{normalize-space(root/myNameSpace)}">bar</xsl:element>
    </xsl:for-each>
  </xsl:element>

  <xsl:element name="newRoot" namespace="{normalize-space(root/myNameSpace)}">
    <xsl:element name="elementOk"
namespace="{normalize-space(root/myNameSpace)}">foo</xsl:element>
    <xsl:for-each select="root/list/listelem">
      <xsl:element name="hardCodedUrl"
namespace="http://test.dynamic.url">bar</xsl:element>
    </xsl:for-each>
  </xsl:element>
</xsl:template>
</xsl:stylesheet>

Output:
<?xml version="1.0" encoding="UTF-8"?>
<newRoot xmlns="http://test.dynamic.url">
<elementOk>foo</elementOk>
<elementError xmlns="">bar</elementError>
<elementError xmlns="">bar</elementError>
</newRoot>
<newRoot xmlns="http://test.dynamic.url">
<elementOk>foo</elementOk>
<hardCodedUrl>bar</hardCodedUrl>
<hardCodedUrl>bar</hardCodedUrl>
</newRoot>
