// Mojo services and applications are identified by structured "names", of the
// form:
//
//    type:path.
//
// The type field tells the shell how to load the application. Two types are
// currently recognized:
//
//  mojo
//   Represents an application packaged as a .mojo, launched from the
//   NativeRunner launch path. .mojo files are assumed to live alongside the
//   shell executable at a path matching <path>/<path>.mojo. .mojo applications
//   have a MojoMain() entrypoint that receives a handle to a ShellClientRequest
//   that must be bound to enable further communication with the shell.
//
//  exe
//   Represents a native executable on the host platform, expected to live
//   alongside the shell executable. Executables launched via this mechanism are
//   passed a handle to the shell on the command line and are expected to bind
//   a ShellClientRequest enabling further communication with the shell. The
//   path component contains the executable name, minus any platform-specific
//   extension.
//
// Other types may be supplied but are not recognized by any of the
// NativeRunners, and as such custom loaders must be specified for such names.
//
// Any name type may serve as an alias for any other name type. Aliasing is
// resolved implicitly by the Shell.

// Returns true if the name is a valid form, i.e. type:path. path cannot start
// with a "//" sequence. These are _not_ urls.
