How to create FIXML message with repeating groups using XSLT

<?xml version="1.0" encoding="utf-8"?> 
<FIXTradeStifel> 
	<UpdateReasonsCount>3</UpdateReasonsCount> 
		<UpdateReasons> 
			<anyType>Price</anyType> 
			<anyType>Principal</anyType> 
			<anyType>Net</anyType> 
		</UpdateReasons> 
		<UpdateValues> 
			<anyType>10.00</anyType> 
			<anyType>10000.00</anyType> 
			<anyType>10000.00</anyType> 
		</UpdateValues> 
</FIXTradeStifel>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:output method="xml"/>
	<xsl:template match="/">
		<FIXMessage>

				</xsl:for-each>
			</g6041>
		</FIXMessage>
	</xsl:template>
</xsl:stylesheet>
