/// Options
///
/// Each of the definitions above may have "options" attached.  These are
/// just annotations which may cause code to be generated slightly differently
/// or may contain hints for code that manipulates protocol messages.
///
/// Clients may define custom options as extensions of the *Options messages.
/// These extensions may not yet be known at parsing time, so the parser cannot
/// store the values in them.  Instead it stores them in a field in the *Options
/// message called uninterpreted_option. This field must have the same name
/// across all *Options messages. We then use this field to populate the
/// extensions when we build a descriptor, at which point all protos have been
/// parsed and so all extensions are known.
///
/// Extension numbers for custom options may be chosen as follows:
/// * For options which will only be used within a single application or
///   organization, or for experimental options, use field numbers 50000
///   through 99999.  It is up to you to ensure that you do not use the
///   same number for multiple options.
/// * For options which will be published and used publicly by multiple
///   independent entities, e-mail protobuf-global-extension-registry@google.com
///   to reserve extension numbers. Simply provide your project name (e.g.
///   Objective-C plugin) and your project website (if available) -- there's no
///   need to explain how you intend to use them. Usually you only need one
///   extension number. You can declare multiple options with only one extension
///   number by putting them in a sub-message. See the Custom Options section of
///   the docs for examples:
///   <https://developers.google.com/protocol-buffers/docs/proto#options>
///   If this turns out to be popular, a web service will be set up
///   to automatically assign option numbers.

    /// - A location may refer to a repeated field itself (i.e. not to any
    ///   particular index within it).  This is used whenever a set of elements are
    ///   logically enclosed in a single code segment.  For example, an entire
    ///   extend block (possibly containing multiple extension definitions) will
    ///   have an outer location whose path refers to the "extensions" repeated
    ///   field without an index.
    /// - Multiple locations may have the same path.  This happens when a single
    ///   logical declaration is spread out across multiple places.  The most
    ///   obvious example is the "extend" block again -- there may be multiple
    ///   extend blocks in the same scope, each of which will have the same path.
    /// - A location's span is not always a subset of its parent's span.  For
    ///   example, the "extendee" of an extension declaration appears at the
    ///   beginning of the "extend" block and is shared by all extensions within
    ///   the block.
    /// - Just because a location's span is a subset of some other location's span
    ///   does not mean that it is a descendant.  For example, a "group" defines
    ///   both a type and a field in a single declaration.  Thus, the locations
    ///   corresponding to the type and field and their components will overlap.
    /// - Code which tries to interpret locations should probably be designed to
    ///   ignore those that it doesn't understand, as more types of locations could
    ///   be recorded in the future.
