That's the expected behaviour.

Matching is done against the namespace URI, not the prefix.

This stylesheet is invalid since the ns namespace prefix isn't declared.

xsltproc 0.5.0 (I haven't compiled any later release yet) returns:
ptittom:~$ xsltproc namespace.xsl namespace.xml 
xsl: pattern, no namespace bound to prefix ns

  WRONG

As do SAXON and Xalan:
ptittom:~$ java -cp saxon/saxon.jar com.icl.saxon.StyleSheet namespace.xml
namespace.xsl 
Error at xsl:template on line 7 of file:/home/ptittom/namespace.xsl:

One can notice xsltproc (maybe it has changed since 0.5.0) doesn't consider
this error a fatal error and doesn't stop processing.
