If you didn't find any connection (though the definition of apposition was quite explicit), here's one more definition:
http://www.merriam-webster.com/dictionary/apposition

a grammatical construction in which two usually adjacent nouns having the same referent stand in the same syntactical relation to the rest of a sentence (as the poet and Burns in “a biography of the poet Burns”)
Ms in Ms Merkel performs the same identifying function as poet in poet Burns. It is true that they identify the person according to a different criterion (marital satus in the former and occupation in the latter), but the type of criteria doesn't change its identifying/differentiating nature.
