 	Note: Multi-word keywords in CSS usually separate their component words with hyphens.
 	''<color>/currentcolor'' doesn't, because (deep breath)
-		it was originally introduced in SVG
-		as a property value, "current-color" with the usual CSS spelling.
-		It (along with all other properties and their values)
-		then became presentation attributes and attribute values,
-		as well as properties,
-		to make generation with XSLT easier.
-		Then all of the presentation attributes were changed
-		from hyphenated to camelCase, because the DOM
-		had an isse with hyphen meaning "minus".
-		But then, they didn't follow CSS conventions
-		anymore so all the properties and property values
-		that were <em>already</em> part of CSS were changed back to hyphenated!
-		''<color>/currentcolor'' was not a part of CSS at that time, so remained camelCased.
