xml data in a param?

Hello all...

ok...i'm kinda stupid...I'm trying to pass xml data into my xslt as a
param, and for testing purposes declaring it statically in my xslt..

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:param name="siteIDString" select="'<?xml
version="1.0"?><favs><site
id='11111111'><doc>00000008</doc><doc>00000002</doc><doc>00000005</doc><doc>11111114</doc><doc>14564444</doc><doc>14564442</doc><doc>00000004</doc></site><site
id='1'><doc>1</doc><doc>22</doc></site></favs></xsl:param>'"/>
	<xsl:variable name="siteDoc" select="document($siteIDString)"/>

	<xsl:template match="/">
		<xsl:apply-templates select="aspect"/>
	</xsl:template>

	<xsl:template match="aspect">
		<favorite>
			<xsl:for-each select="site">
				<xsl:choose>
					<xsl:when test="@id = $siteDoc//site/@id">
						<xsl:apply-templates select="." mode="goodSite"/>
					</xsl:when>
				</xsl:choose>
			</xsl:for-each>
		</favorite>
	</xsl:template>

I keep getting an error that the "<" character is not allowed as
within a select...

Sorry if this is an elementary question...

Thanks for the help...

Cal.
