/// - Parameters:
///   - textDocument: The document in which to lookup the symbol location.
///   - position: The document location at which to lookup symbol information.
///   - includeDeclaration: Whether to include the declaration in the list of symbols.

/// - Returns: An array of locations, one for each reference.
