!!!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
