Ordinatio Sacerdotalis is not a dogma.  It is an edict to temporarily stop official discussion of the issue.  It is entirely written in past and present tense, and says NOTHING about what the Church can or cannot do in the future.  Therefore, it is "definitive" for the past and the present, but not the future, since it says NOTHING about the future.  I think it was a tragic mistake, no matter how well intended.  I believe in my heart that the ordination of women will be for the glory of God and the good of souls, patriarchal obfuscations to the contrary notwithstanding.
