Some components by a user may contain all caps when it is an abbreviation, eg. <YMCA />, which is still technically valid PascalCase.

In the documentation it specifies that <TEST_COMPONENT> should throw a warning. Obviously it would be impossible for the parser to tell whether a component in all caps is a word or an abbreviation (unless, eg, it looked for punctuation, but even then still not certain).

Would you consider an optional parameter passed to the react/jsx-pascal-case rule to allow all-caps components, or perhaps to specify which component names are allowed to be all caps, would be appropriate?

I'm thinking:

"react/jsx-pascal-case": [2, {"all-caps": true} ]

or

"react/jsx-pascal-case": [2, {"exceptions": "YMCA"}]

Obviously it should still throw an error on components <ymca> or <yMCA>. I'm not sure what solution would best integrate with the rest of the project so open to your thoughts. I use several of these abbreviated components throughout many of my apps.
