Group by Element based on Attribute inside container

I am new to the XML/XSL world, I hope the terminology of the subject line
correctly reflects my problem. I am using 1.0 and can not use 2.0. All client
machines will use IE6 on Windows XP machines to view the report. I can not
alter the XML output/format. I can only create an XSL to show the data in a
report.

I have read and tried many examples this week concerning the Muenchian method.
The examples are good but the XML format used in the examples seems simpler
than the format I am using. I have made great effort in altering Jenni
Tennison's example. The best I can do for output is based on this example
http://www.zvon.org/xxl/XSLTreference/OutputOverview/xslt_key_frame.html
However it does not group.

What I need is to group by (and sort) the valve number, list the inspections
for that valve sorted by the most recent date (if sort by a date is possible).
For example:
ValveNumber: 992
DateInspected1 InspectedBy1 RepairsMade1 ...
DateInspected2 InspectedBy2 ReapirsMade2 ...
ValveNumber: 993
DateInspected1 InpsectedBy1 ReapirsMade1 ...

Some of the hurdles I need to overcome are how to assign the correct variables
for the Key and properly format the Count or GenerateID method as described in
Jenni's examples.

Some of my efforts:
<xsl:stylesheet xmlns:xsl = "http://www.w3.org/1999/XSL/Transform" version =
"1.0" >
            <xsl:output method = "text" />

            <xsl:key name = "keyFacilityID" match = "ObjectClassField" use =
"@name" />

            <xsl:template match = "/" >
                        <xsl:apply-templates select =
"ObjectClassField[count(.| key('keyFacilityID','Valve
Number')[1])=1]"><!--"key('keyFacilityID','Valve Number')"-->
                        <xsl:sort/>
                        </xsl:apply-templates>
            </xsl:template>

            <xsl:template match = "ObjectClassField" >
                        <xsl:text >
                        </xsl:text>
                        <xsl:value-of select = "@name"/>
                        <xsl:text >
                        </xsl:text>
                        <xsl:value-of select = "." />
            </xsl:template>
</xsl:stylesheet>
