As far as I know xsl:key is a top-level element. But you can acchieve
what you want using something like:

<xsl:key name="playerResultLookupByWeek" match="playerResult"
use="concat(@player, '-', ../@week)" />

Kind regards,

Interesting. It appears to work fine as it is for the first
iteration. The trouble with putting the key declaration
outside the template is that I would then not be able to
apply the [@week=$week] predicate to the match="playerResult"
which is what causes the lookup to be restricted to one of
the two sets of week data. How could I get around this, other
than hardcoding 2 keys, one for each week? I'd prefer not to
do that because if any new weeks are added to the XML then
they would not be included in the output.
