TextDocumentIdentifier

https://github.com/Microsoft/language-server-protocol/blob/master/protocol.md#textdocumentidentifier

Text documents are identified using a URI. On the protocol level, URIs are
passed as strings. The corresponding JSON structure looks like this:

interface TextDocumentIdentifier {
    /**
     * The text document's URI.
     */
    uri: string;
}
-}
data TextDocumentIdentifier =
  TextDocumentIdentifier
    { _uri :: Uri
    } deriving (Show, Read, Eq)

TextDocumentItem

    New: An item to transfer a text document from the client to the server.

    /**
     * The text document's URI.

    uri: string;

    /**

     * change, including undo/redo).
