Yes, the namespace axis is deprecated in XPath 2.
That means we need different metastylesheets for XSLT-based implementations.

Without looking for this article, I think the pure XSLT2 solution is
something like this:
<xsl:for-each select="get-in-scope-namespaces(/*)">
   <xsl:namespace name="{.}">
      <xsl:value-of select="get-namespace-uri-for-prefix(/*, .)" />
   </xsl:namespace>
</xsl:for-each>

Note: get-in-scope-namespaces of the current (May 2) draft will be renamed
to get-in-scope-prefixes.

I'm afraid I don't understand your point.
XPath expressions that select elements from a certain namespace must use
prefixed names. If the targetted elements are in the null (empty) namespace
then clearly no prefix must be used.
The question is if Schematron needs this additional <ns> element to
declare namespaces. I don't think so. I cannot remember why <ns> was 
introduced:
- because nobody was aware of <xsl:copy-of select="namespace::*" /> ?
- because this solution didn't work with some XSLT processors?

Do you see any (semantic) difference between
<schema xmlns:p="urn:my-personal-namespace" ...>
and
<schema ...>
  <ns uri="urn:my-personal-namespace" prefix="p" />
  
?

Cheers,
Oliver
