	// TODO: change to use race; https://github.com/FamilySearch/gedcomx/issues/295
	{
	regex: /^(color or )race$/,
	type: 'http://gedcomx.org/Ethnicity'
	},
	{
	regex: /^ethnicity\/ nationality$/,
	type: 'http://gedcomx.org/Ethnicity'
	},

A few issues:

• Change the race fact type to http://gedcomx.org/Race
• Fix the race regex by adding a ? after (color or)
• Verify the ethnicity regex; it looks weird
