Do you expect the author of the XSLT stylesheet to read the schema and 
author an appropriate XSLT stylesheet? Someone skilled with schemas and 
stylesheet can certainly do that.
Or do you expect the XSLT stylesheet to be generic and pull in the 
schema and then based on the schema to generate the output? That is far 
from being trivial, with the complexity the W3C XML schema language has.

Here is my attempt to write a stylesheet based on the XML input and the 
schema you have provided, it simply copies everything recursively 
besides the 'c' and 'z' elements:

<xsl:stylesheet
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
   xmlns:test="http://test/"
   version="1.0">

   <xsl:template match="@* | node()">
     <xsl:copy>
       <xsl:apply-templates select="@* | node()"/>
     </xsl:copy>
   </xsl:template>

   <xsl:template match="test:c | test:z"/>

</xsl:stylesheet>

That way you get

<?xml version="1.0" encoding="UTF-8"?>
<a xmlns="http://test/" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://test/ test2009081401Xsd.xml">
    <b>Node B</b>

    <m>
       <x>Node X1</x>
       <y>Node Y1</y>

       <m>
          <x>Node X2</x>
          <y>Node Y2</y>

       </m>
    </m>
</a>
