Let's clear up a couple small items at first. The proposed key declaration
is:
<xsl:key name="keyCodeLists"
match="//odm:CodeList"
use="concat(ancestor::odm:Study/@OID,
ancestor::odm:MetaDataVersion/@OID, @OID)"/>
That looks good, except that match patterns don't need the leading //, as
they will match all occurrences throughout the tree anyway. However, you
need the // in a select expression like
count(//odm:CodeList)
if you were trying to find out how many "rows" the key table ought to
have.
The proposed lookup is:
key('items', concat($a, $b, $c))
but you probably meant
key('keyCodeLists', concat($a, $b, $c))
because the names need to match. Also, check that uppercase/lowercase is
correct everywhere.
After checking all that, tell us if you still have a problem.
