Update of highway classification in Caces (from Track to Residential). Reflect track from Buseco to Las Carangas. Reflect El Rebollal as place. Reflect drinking water in Buseco and El Pando. Reflect restaurant Chema close to Las Guertonas.

Hopefully answering my own question on how to tag certain highways with a specific route name (different than its official name), I believe this is done via "Relation".
