/**
 * `ClientCapabilities` now define capabilities for dynamic registration, workspace and text document features the client supports.
 * The {@link #experimental} can be used to pass experimental capabilities under development.
 * For future compatibility a `ClientCapabilities` object literal can have more properties set than currently defined.
 * Servers receiving a `ClientCapabilities` object literal with unknown properties should ignore these properties.
 * A missing property should be interpreted as an absence of the capability.
 * If a property is missing that defines sub properties all sub properties should be interpreted as an absence of the capability.
 * <p>
 * Client capabilities got introduced with the version 3.0 of the protocol. They therefore only describe capabilities that got introduced in 3.x or later.
 * Capabilities that existed in the 2.x version of the protocol are still mandatory for clients. Clients cannot opt out of providing them.
 * So even if a client omits the {@link TextDocumentClientCapabilities#synchronization}
 * it is still required that the client provides text document synchronization (e.g. open, changed and close notifications).
