The proposal of SemanticHighlighting uses a versioned text document
identifier, but there is a suggestion to be more coherent with other
existing requests and use text document identifier instead (non versionned).
See here: https://github.com/microsoft/vscode-languageserver-node/pull/367/files#r225879268
The clangd language server implements the non versioned version.
Existing code was returning errors with clangd because
SemanticHighlightingParams::isValid would return false because of the
missing version field.

The result of the document symbol request was a flat list of symbols
until version 3.10.0 of the Protocol. The new result type also added
whether a symbol is deprecated and what text should get selected
when a symbol is activated in the IDE UI.

The language server protocol is used to transport language specific
information needed to efficiently edit source files. For example
completion, go to operations and symbol information. These information
are transferred via JSON-RPC. The complete definition can be found under
https://microsoft.github.io/language-server-protocol/specification.
This language server protocol support consists of two major parts, the
C++ representation of the language server protocol, and the client part
for the communication with an external language server.
The TypeScript definitions of the protocol interfaces are transferred to
C++ classes. Those classes have getter and setter for every interface
value. Optional values from the protocol are represented by
Utils::optional<ValueType>. The JSON objects that are used to transfer
the data between client and server are hidden by a specialized
JsonObject class derived from QJsonObject. Additionally this JsonObject
provides a validity check that is capable of creating a detailed error
message for malformed, or at least unexpected JSON representation of the
protocol.
The client is the interface between Qt Creator and language server
functionality, like completion, diagnostics, document and workspace
synchronization. The base client converts the data that is sent from/to
the server between the raw byte array and the corresponding C++ objects.
The transportat layer is defined in a specialized base client (this
initial change will only support stdio language server). The running
clients are handled inside the language client manager, which is also
used to connect global and exclusive Qt Creator functionality to the
clients.
