[eml-dev] givenName element uses

[inigo san gil]

for the sake of proper granularity, and in an attempt to disambiguate 
the interpretation of the contents of <givenName>, would eml-dev 
consider reducing the cardinality of the element to 0 to 1, and adding a 
middleName optional element?  of course, if middleName sounds to 
straightforward you can use some other semantical contortion to refer to 
such concept - say saddleName :)

the ambiguity causes trouble when matching subjects, migration to DBs, etc.
