Level 1 should be remain an unconstrained string. Although it does not exactly
hurt to have an optional language attribute on it, I think I agree with Anna
and Chris in that that start to blur the distinction between Level 1 and 2.
However, if in the case of Literature references we define Level 1 as "any
unconstrained form of literature citation acceptable in scientific citations"
then the string may include abbreviated or non-abbreviated journal/source
information, it may include various other metadata such as "date last seen" for
online-references, and it may include free-form
translation/transcription/transliteration data such as "Flora of Siberia,
Moskau 19XX (in Russian).".

In the case of references, it would be very useful to define level 2 as
sufficiently rich (in structure and detail) to allow the generation of
unconstrained reference text according to the various common citation formats -
a job software like ReferenceManager or EndNote is commonly used for.
