[Obo-format] order of tags in Typedef's

[Erick A. <eri...@gm...>]

Hi,

which should be the ordering of the following tags?

 intersection_of
 union_of
 disjoint_from

in Typedef's?

The spec (http://www.geneontology.org/GO.format.obo-1_4.shtml ) gives
only a hit about the order of those tags for the Terms but not
Typedef's.

thanks,
Erick
