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:

    <bkey>3 5 6</bkey>

...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.

   <value key="1">60</value>
   <value key="2">51</value>
   <dir key="bla">
      <value key="2">66</value>
      <value key="1">44</value>
