I must say that using the key as an attribute surprised me when I first
saw it, but it's not so bad.
I want to be able to filter through these files with XPath, mostly, and
after playing with a few of the alternatives on the table, it seems like
your original format is the best, if you want to have a uniform structure
that conforms to a generic DTD.
Something that would simplify XPath/XSLT processing in certain cases is
having a direct output of keys into elements:
<akey>
<anotherkey>0</anotherkey>
<subdirectory>
<bkey>3 5 6</bkey>
</subdirectory>
</akey>
...but I can see how this would descend into chaos pretty quickly if you
wanted to be generic.
So my vote is for your description as shown below.
<pool>
<value key="1">60</value>
<value key="2">51</value>
<dir key="bla">
<value key="2">66</value>
<value key="1">44</value>
</dir>
</pool>
