Link to navigate to a document at line X column Y in MD documentation (hover)

Eclipse JDT documentation hovers have links to navigate to a document, line X column Y or open document and select a range in it. The link is a hyperlink with some special protocol. The URL handler for this protocol is registered and handles a click as navigate to source code at a position provided in the URL. Many LSP clients (VSCode, Atom and soon Eclipse) have support such URLs. These URL's are special for each client (vscode://, atom:// etc.). If LSP could define some universal format for such URLs (lsp://file:///Users/abv/project/src/Main.java?line=X&column=Y) then clients can convert this URL into client specific URL and provide the behaviour described above from LSP hovers.
