copy texts from wiki, license problems

[Klumbumbus]

I would like to add the descriptions of the values of ​Key:leaf_cycle from the wiki (since semi_evergreen and semi_deciduous are not self-explaning). However this seems not allowed, because of the cc-by-sa 2.0 license of the wikitexts. Would it be enough, if we add the text Parts of the texts used in presets taken from the osm wiki http://wiki.openstreetmap.org CC BY-SA 2.0 (or similar) to the contributors or license tab of the about window?
