Being new to XSLT I'm a little unsure of exactly what the
pattern in the
'use' attribute value in the xsl:key element is doing.
If you want to index all employees by their works number, you do
<xsl:key name="k" match="employee" use="works-number"/>
and then to find an employee with works number 517541 you do
key('k', '517541')
The use attribute can be any XPath expression, so if you want to index
employees on the number of events they have in their promotion history, you
can do
<xsl:key name="k" match="employee" use="count(promotion-history/event)"/>
and then
key('k', 3)
will find all employees with three such events.
