Also, Mike earlier suggested using xsl:for-each-group, which offers a 
nice solution:

<xsl:for-each-group select="//*" group-by="name()">
  <xsl:text>&#xA;&#xA;</xsl:text><!-- two new lines -->
  <xsl:value-of select="current-grouping-key()"/>
  <xsl:for-each-group select="current-group()/@*" group-by="name()">
    <xsl:text>&#xA;  </xsl:text><!-- new line, indent -->
    <xsl:value-of select="current-grouping-key()"/>
  </xsl:for-each-group>
</xsl:for-each-group>

This is somewhat different from what was posted, in that it lists 
distinct attributes that may appear with each element, but this is 
usually useful information -- and if you do want a list of attributes 
appearing absolutely, just do the element thing again, except 
selecting "//@*". (Also, I haven't taken the trouble to make HTML out of it.)

This approach can be taken one more step to report values of 
attributes, or repeating values of attributes (which sometimes makes 
for less noise).

Cheers,
Wendell
