9*1212f9a0SAndroid Build Coastguard Worker        variable using select attribute.  Reference as [$n] -->
10*1212f9a0SAndroid Build Coastguard Worker  <!-- Author: Paul Dick -->
11*1212f9a0SAndroid Build Coastguard Worker  <!-- Note: When a variable is used to select nodes by position,
12*1212f9a0SAndroid Build Coastguard Worker             be careful not to do:
13*1212f9a0SAndroid Build Coastguard Worker             <xsl:variable name="n">2</xsl:variable>
14*1212f9a0SAndroid Build Coastguard Worker                ...
15*1212f9a0SAndroid Build Coastguard Worker             <xsl:value-of select="item[$n]"/>
16*1212f9a0SAndroid Build Coastguard Worker             This will output the value of the first item element,
17*1212f9a0SAndroid Build Coastguard Worker             because the variable n will be bound to a result tree fragment,
18*1212f9a0SAndroid Build Coastguard Worker             not a number. Instead, do either
19*1212f9a0SAndroid Build Coastguard Worker
20*1212f9a0SAndroid Build Coastguard Worker             <xsl:variable name="n" select="2"/>
21*1212f9a0SAndroid Build Coastguard Worker                ...
22*1212f9a0SAndroid Build Coastguard Worker             <xsl:value-of select="item[$n]"/>
23*1212f9a0SAndroid Build Coastguard Worker                or
24*1212f9a0SAndroid Build Coastguard Worker             <xsl:variable name="n">2</xsl:variable>
25*1212f9a0SAndroid Build Coastguard Worker                ...
