I think that's reversed: DSA2 is quickly becoming a de facto standard, 
but it is not a de jure standard.

De facto: "in fact".  De jure: "in law".  De jure standards exist on 
paper but are not respected, de facto standards exist in reality but may 
not exist on paper.

If I am mistaken as to what you meant to say, please correct me.  :)
