Use a partial (non-administrative) relation for validations instead

[Crashillo]

The current config for Basque country and Navarre are the following:

osmose-backend/osmose_config.py

Lines 1914 to 1918 in 7421fa1

	es_prov('comunidad_foral_de_navarra', 6429242, 'ES-NA', proj=32630, language=['es', 'eu'], multilingual_style='sp_eu', hydro=['Ebro'])
	es_prov('euskadi/alava', 349011, 'ES-VI', proj=32630, language=['eu', 'es'], multilingual_style='sp_eu', hydro=['Ebro'])
	es_prov('euskadi/vizcaya', 349034, 'ES-BI', proj=32630, language=['eu', 'es'], multilingual_style='sp_eu', hydro=['Cantábrico Oriental'])
	es_prov('euskadi/guipuzcoa', 349015, 'ES-SS', proj=32630, language=['eu', 'es'], multilingual_style='sp_eu', hydro=['Cantábrico Oriental'])

Since we agreed in the forum to simplify the multilingual names, the config will be:

# no multilingual at all for euskadi
es_prov('euskadi/alava', 349011, 'ES-VI', proj=32630, language=['eu', 'es'], hydro=['Ebro']) 
es_prov('euskadi/vizcaya', 349034, 'ES-BI', proj=32630, language=['eu', 'es'], hydro=['Cantábrico Oriental']) 
es_prov('euskadi/guipuzcoa', 349015, 'ES-SS', proj=32630, language=['eu', 'es'], hydro=['Cantábrico Oriental']) 

# split navarre in two regions: spanish and basque speaking areas
es_prov('comunidad_foral_de_navarra_eu', [9089335, 9089318], 'ES-NA', proj=32630, language=['es', 'eu'], hydro=['Ebro']) 
es_prov('comunidad_foral_de_navarra_es', 9089396, 'ES-NA', proj=32630, language=['eu', 'es'], hydro=['Ebro']) 

Euskadi would be easy: just like Catalonia, Balearic islands or Galicia.

But pay attention to the Navarra relation IDs: basque areas (https://osm.org/relation/9089335 and https://osm.org/relation/9089318), spanish area (https://osm.org/relation/9089396). No multilingual rule in any case.

Would it be possible to make this happen? Would it work? If not, how could we approach it in terms of coding?
