Hello Biray, 
This is pretty much conjecture but:

One approach would be to use recursion: every time you come across a new
attribute value, call the template you're in with the updated list of values
encountered as a parameter. The trouble here would be that it makes it
difficult to apply other templates while you're stuck in a recursion loop.

I wonder if you could use a key? How about
<xsl:key name="firsts"
match="//Content[not(./preceding::Content/@ContentText=./@ContentText)]"
use="@ContentText"/>

should give you a handle on all the Content nodes with ContentText
attributes without precedent. Then when you were matching the Content nodes
you would set the colour using 

<xsl:choose>
<xsl:when test="(count(. | key('firsts',@ContentText)) = 1)">
	- do whatever with red here
</xsl:when>
<xsl:otherwise>
	- do whatever in black here
</xsl:otherwise>
</xsl:choose>

This works across ALL Content nodes.
