Conditional display

Hi.
I am new to xsl-fo and had a small doubt as to how my xsl should look if my
input xml is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<PlanPerformance>
	<FundPerformance>
		<FundId>1</FundId>
		<FundName>Fund1</FundName>
		<FundRate>
			<FundId>1</FundId>
			<FundName>FundOne</FundName>
			<SubFundRate>
				<FundId>2</FundId>
				<FundName>Fund2</FundName>
			</SubFundRate>
			<SubFundRate>
				<FundId>3</FundId>
				<FundName>Fund3</FundName>
			</SubFundRate>
		</FundRate>
	</FundPerformance>
	<FundPerformance>
		<FundId>2</FundId>
		<FundName>Fund2</FundName>
	</FundPerformance>
</PlanPerformance>

there can be only 1 FundRate tag within 1 FundPerformance.

I want to have a display like follows on my pdf.

Fund Id   Fund Name
-----------   ----------------
1	FundOne	(Name picked from FundRate as FundRate is present)
2	Fund2
3	Fund3
	2	        Fund2	(Name picked from FundPerformance as FundRate is not
present)

	Can someone please help me out in this case?

	Thanks,
	Praful.
