The documentation ve.dm.MWInlineExtensionNode for says:
extensionsName
Name of the extension and the parser tag name
However the property is actually only used for the parser tag name, and has no relationship to the name of the extension. The current documentation is confusing because new developers may not understand how to use this property correctly.

Despite its name, the extensionName static property is only used for the parser tag's name, and we don't really care about the name of the extension. VisualEditor itself has the class ve.dm.MWPreNode, which sets .extensionName = 'pre', to support MediaWiki's built-in <pre> tags.
You should be able to just define two classes, one with .extensionName = 'pgn' and another with .extensionName = 'fen'. If you can confirm that this works for you, I suppose we should just correct the documentation in ve.dm.MWExtensionNode?
Thanks @matmarex for clearing this up for me and for the additional example (I had only seen Score and Math). I can confirm that your solution works. Updating the documentation would be very helpful to avoid this confusion. I've update the task to that effect.
