Algorithm for turning Oahpa entries
- revert all <l> - <t(f)> pairs, for which the tg HAS a sematics element. 
 - unify for identical instances of former <t(f)>, now <l>
 - remove all <l> (i.e., <e>) for <l> with no stat="pref" tag
 - keep the rest of the Norwegian lemmas 
 - remove multiple stat="pref" tags manually (Comment: This can't be the case!)
 
Issues
- what about attribute oa? 
 - what about lacking this attribute?

Principle for dictionary conversion.
- Turn smanob to nobsma 
 - Thereafter, manually remove superfluous <t> synonyms in smanob tg-s
 - in the new nobsma, unify according to lemma 
 - for lemma pairs with conservative/radical Bokmål, pict the (e.g.)
 conservative as the lemma, and make a pointer from the radical one 
Cf. the following example:
vatn -> vann vann 1. (væske) tjaetsie 2. (innsjø) jaevrie jaevrie innsjø tjaetsie (væske) vann
