I have a basic query which I'm having trouble with (XSLT1.0)

I have written (nicked) an external function that gives me the max value of a set of values, it works lovely and I call it from within my main stylesheet.

simple source xml
<TABLE>
<RECORD>
<FLAG>N</FLAG>
<IP>
<ID>2</ID>
<NAME>jenny</NAME>
</IP>
</RECORD>
<RECORD>
<FLAG>N</FLAG>
<IP>
<ID>7</ID>
<NAME>dick</NAME>
</IP>
<IP>
<ID>3</ID>
<NAME>jim</NAME>
</IP>
<IP>
<ID>5</ID>
<NAME>amanda</NAME>
</IP>
</RECORD>
<RECORD>
<FLAG>Y</FLAG>
<IP>
<ID>3</ID>
<NAME>keri</NAME>
</IP>
<IP>
<ID>1</ID>
<NAME>mark</NAME>
</IP>
<IP>
<ID>2</ID>
<NAME>jane</NAME>
</IP>
</RECORD>
</TABLE>

What i'm after is the person's name who's record is flagged with a Y and who's ID is the highest (hence the max function).

My XSLT stylesheet looks like this which gives me the correct max value, 3 in this instance however I need the name. Anyone help me out of a simple pickle?

....snip
<NAME>
<xsl:call-template name="math:max">
<xsl:with-param name="values" select="/RECORD/[FLAG = 'Y']/IP/ID"/>
</xsl:call-template>
</NAME>
....snip

Could use a variable to store the value.
<xsl:variable name="maxValue">
<xsl:call-template name="math:max">
<xsl:with-param name="values" select="/RECORD/[FLAG = 'Y']/IP/ID"/>
</xsl:call-template>
</xsl:variable>
...

<xsl:value-of select="/RECORD/[FLAG = 'Y']/IP[ID=$maxValue]/NAME"/>
