Default namespace in xscript produces error - Element or attribute do not match QName production: QName::=(NCName':')?NCName

           Summary: Default namespace in xscript produces error - Element or
                    attribute do not match QName production:
                    QName::=(NCName':')?NCName
           Product: Cocoon 2
           Version: 2.1
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: core
        AssignedTo: dev@cocoon.apache.org
        ReportedBy: alex.rudnev@dc.gov


When you try to use value of xscript variable in xsp, which has default 
namespace declaration, it crashes with the following error:

Element or attribute do not match QName production: 
QName::=(NCName':')?NCName

This code works:
...
<xscript:variable name="test-xml">
  <bla-bla:test xmlns:bla-bla="urn:some-url">!!!</ bla-bla:test> 
</xscript:variable>
<xscript:get name="test-xml" />
...
, and this one doesn't:
...
<xscript:variable name="test-xml">
  <test xmlns="urn:some-url">!!!</test>
</xscript:variable>
<xscript:get name="test-xml" />
...

Possible reason could be in usage of 
org.apache.cocoon.components.xscript.StringBufferContentHandler, which is not 
being used anywhere else and looks like obsolete (not deprecated). It 
handles "xmlns:*" attributes in some special way, but not "xmlns".
