+//
+// For example, say we have a file like:
+//   message Foo {
+//     optional string foo = 1;
+//   }
+// Let's look at just the field definition:
+//   optional string foo = 1;
+//   ^       ^^     ^^  ^  ^^^
+//   a       bc     de  f  ghi
+// We have the following locations:
+//   span   path               represents
+//   [a,i)  [ 4, 0, 2, 0 ]     The whole field definition.
+//   [a,b)  [ 4, 0, 2, 0, 4 ]  The label (optional).
+//   [c,d)  [ 4, 0, 2, 0, 5 ]  The type (string).
+//   [e,f)  [ 4, 0, 2, 0, 1 ]  The name (foo).
+//   [g,h)  [ 4, 0, 2, 0, 3 ]  The number (1).
+//
+// Notes:
+// - 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 descendent.  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.
