First of all, the XML is well-formed but doesn't conform to the namespaces
REC, because the prefixes "ino" and "xql" aren't declared. XSLT requires
that the input conforms to the namespaces REC. There has been some
discussion on the Tamino forum at http://www.tamino.com/ on how best to deal
with this. One idea is to put a SAX filter in front of the XSLT processor,
another is to wrap the XML inside another element that contains the
namespace declarations, which you can do by treating the real document as an
entity:

<wrapper xmlns:ino="..." xmlns:xql="...">&realdoc;</wrapper>

Declaring the namespace prefixes in the stylesheet doesn't solve the
problem.

Once you've constructed a well-formed document, you can achieve the copy you
want by writing:

<?xml version="1.0"?>
<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
  xmlns:ino="http://namespaces.softwareag.com/tamino/response2"
  xmlns:xql="http://metalab.unc.edu/xql/">

<xsl:output method="xml" indent="yes" omit-xml-declaration="yes" />

<xsl:template match="xql:result">
  <xsl:for-each select="*">
     <xsl:variable name="ino-id" select-"generate-id(@ino:id)"
     <xsl:copy-of select="@*[generate-id()!=$ino-id]"/>
     <xsl:copy-of select="node()"/>
  </xsl:for-each>
</xsl:template>

</xsl:stylesheet>

You don't need exlcude-result-prefixes; that only affects namespaces written
when copying a literal result element from the stylesheet, and this
stylesheet doesn't contain any literal result elements.
