more attribute fun...

After some great responses from people (thank you), I
found some great solutions for adding an offset to a
value within an attribute. Some people suggested using
the attribute template method. IE:

<path d="M 35, {$y_offset + 25} ..."/>

This worked great, but now I was wondering about
calculating something in an attribute and then
outputing the result. What I mean by this is something
to the effect of:

<path d="M 35... fill="{fill_percentage > 90 ? green :
yellow}" />

so having some sort of conditional that I can use to
check the percentage filled and output a different
color if greater than 90 percent. Can I do something
like this? Or am I going to have to go to the older
method of doing things, ie:

<path>
    <xsl:attribute name="fill">
        <xsl:choose>
          <xsl:when test="$fill_percentage > 90">
            <xsl:text>green</xsl:text>
          </xsl:when>
            .
            .
            .
        </xsl:choose>
    </xsl:attribute>
</path>

Thanks for any help or suggestions,

Bryan
