RE: RE: unwanted and non prefix namespaces in output

I don't know what XSLT processor you're using, but the output I'm seeing
from Saxon (which I believe is correct) starts:

<sequence xmlns:ads="http://schemas.microsoft.com/ads/2003/sequence"
version="1" description="foo" command="bar">
  
   <sequence version="1" description="Image" command="WIN2000">
    
      <task xmlns="http://schemas.microsoft.com/ads/2003/sequence">

The first <sequence> element is generated from a literal result element in
your stylesheet. It is in no namespace because the stylesheet doesn't put it
in a namespace. It copies the declaration of xmlns:ads from the stylesheet
because that's what literal result elements do.

The second <sequence> element is the same, but it doesn't redeclare
xmlns:ads because that would be redundant.

The <task> element is generated by copying from the source document. The
element is in the ads/2003 namespace because it stays in the same namespace
when you copy it. The original <task> element has an in-scope namespace with
prefix "" and uri "http://....ads/2003/...", so the copied element has one
too.

I think, if I understand your problem description, that you probably want to
write <xsl:copy> where you currently write <sequence>. That way you will get
the namespaces that are in scope for the source element, not those that are
in scope in the stylesheet.

You made a lot of headway in four hours...
