[xsl] variable

["Eric Schenfeld" <ESchenfeld@xxxxxxxxxxx>]

is there a way to change the value of a parameter or a variable after it's been declared?  like with an if statement?

CODE:

		<xsl:param name="color">123456</xsl:param>
		<xsl:if test="ancestor::top_bar">
			<xsl:param name="color">ffffff</xsl:param>
		</xsl:if>
		<xsl:if test="ancestor::bottom_bar">
			<xsl:param name="color">000000</xsl:param>
		</xsl:if>

It doesn't seem to work with variables or parameters.  is there some other way?
