14554	"The ""Misspelled property value - Value 'Bing' for key 'source' looks like 'bing'"" validator warning should be reversed and demoted, or removed"	moltonel	team	"As mentioned https://lists.openstreetmap.org/pipermail/talk/2017-March/077645.html :

While we do have a ""standard values should be lowercase"" best-practice in OSM, I don't think this should apply to source tags except maybe ""survey"" and ""local_knowledge"" :
* Most source values, like Bing, are proper names and capitalization matters.
* Exact capitalization could be expected/demanded by sources which allow importing into OSM.
* ""Bing"" is twice as frequent as ""bing"" on taginfo, so suggesting the later goes against the general trend.
* Clicking the ""obtain from current layers"" link in the changeset upload form yields ""Bing"", which is inconsistent with the validator warning.
* There's no reason to treat Bing specially, yet the validator doesn't warn about ""Mapbox"" or ""Mapillay"".

The simple way to fix this is to remove the warning altogether, but alternatively:
* The warning should suggest ""Bing"" rather than ""bing""
* The warning should be demoted to a notice
* Other values like ""Mapbox"" etc should be handled similarly (maybe extract the correct values from the imagery definitions ?)"	defect	closed	normal		External preset		fixed	bing
