And in XSLT 1.0:
<xsl:for-each select="//*">
<xsl:for-each select="ancestor-or-self::*/@*">
<xsl:if test="not(position=1)">
<xsl:text>,</xsl:text>
</xsl:if>
<xsl:value-of select=".">
... don't worry about the performance: this is the kind of performance XSLT
engines are built to do.
If your trees really are so big this is ever a problem, it could be helped
by doing a recursive descent and passing parameters along the way:
<xsl:template match="*"/>
<xsl:param name="ancestor-attrs" select="/.."/>
<xsl:variable name="all-attrs" select="@* | $ancestor-attrs"/>
<xsl:for-each select="$all-attrs">
<xsl:if test="not(position=1)">
<xsl:text>,</xsl:text>
</xsl:if>
<xsl:value-of select=".">
</xsl:for-each>
<xsl:apply-templates>
<xsl:with-param name="ancestor-attrs" select="$all-attrs"/>
</xsl:apply-templates>
</xsl:template>
But I wouldn't bother with that unless I had a real reason to.
(Obsessive-compulsive disorder in itself is no good reason.)
Cheers,
Wendell

No problem. In XSLT 2.0:
