+// an `Encoding` which describes how to convert to or from the underlying data.
 //
-// Each encoding also defines the following properties:
+// Each encoding can operate in one of two modes:
 //
-//  * Order-preserving: Does the encoded value sort consistently with the
-//    original typed value? Note that Bigtable will always sort data based on
-//    the raw encoded value, *not* the decoded type.
-//     - Example: BYTES values sort in the same order as their raw encodings.
-//     - Counterexample: Encoding INT64 as a fixed-width decimal string does
-//       *not* preserve sort order when dealing with negative numbers.
-//       `INT64(1) > INT64(-1)`, but `STRING("-00001") > STRING("00001)`.
-//  * Self-delimiting: If we concatenate two encoded values, can we always tell
-//    where the first one ends and the second one begins?
-//     - Example: If we encode INT64s to fixed-width STRINGs, the first value
-//       will always contain exactly N digits, possibly preceded by a sign.
-//     - Counterexample: If we concatenate two UTF-8 encoded STRINGs, we have
-//       no way to tell where the first one ends.
-//  * Compatibility: Which other systems have matching encoding schemes? For
-//    example, does this encoding have a GoogleSQL equivalent? HBase? Java?
+//  - Sorted: In this mode, Bigtable guarantees that `Encode(X) <= Encode(Y)`
+//    if and only if `X <= Y`. This is useful anywhere sort order is important,
+//    for example when encoding keys.
+//  - Distinct: In this mode, Bigtable guarantees that if `X != Y` then
+//   `Encode(X) != Encode(Y)`. However, the converse is not guaranteed. For
+//    example, both `{'foo': '1', 'bar': '2'}` and `{'bar': '2', 'foo': '1'}`
+//    are valid encodings of the same JSON value.
+//
+// The API clearly documents which mode is used wherever an encoding can be
+// configured. Each encoding also documents which values are supported in which
+// modes. For example, when encoding INT64 as a numeric STRING, negative numbers
+// cannot be encoded in sorted mode. This is because `INT64(1) > INT64(-1)`, but
+// `STRING("-00001") > STRING("00001")`.
