If you are stuck with 1.0 then you need to use a key:

<xsl:key name="names" match="*|@*" use="name()"/>

with

<xsl:for-each select="//*|//*/@*">
  <xsl:if test="generate-id(.) = generate-id(key('names', name(.))[1])">
    <xsl:value-of select="local-name()"/>
	
In 2.0 you can use distinct-values() or xsl:for-each-group, but it
always good to learn this technique.
