+ @brief a type for a packed binary type
+
+ This type is a type designed to carry binary data that appears in various
+ serialized formats, such as CBOR's Major Type 2, MessagePack's bin, and
+ BSON's generic binary subtype. This type is NOT a part of standard JSON and
+ exists solely for compatibility with these binary types. As such, it is
+ simply defined as an ordered sequence of zero or more byte values.
+
+ Additionally, as an implementation detail, the subtype of the binary data is
+ carried around as a `std::uint8_t`, which is compatible with both of the
+ binary data formats that use binary subtyping, (though the specific
+ numbering is incompatible with each other, and it is up to the user to
+ translate between them).
+
+ [CBOR's RFC 7049](https://tools.ietf.org/html/rfc7049) describes this type
+ as:
+ > Major type 2: a byte string. The string's length in bytes is represented
+ > following the rules for positive integers (major type 0).
+
+ [MessagePack's documentation on the bin type
+ family](https://github.com/msgpack/msgpack/blob/master/spec.md#bin-format-family)
+ describes this type as:
+ > Bin format family stores an byte array in 2, 3, or 5 bytes of extra bytes
+ > in addition to the size of the byte array.
+
+ [BSON's specifications](http://bsonspec.org/spec.html) describe several
+ binary types; however, this type is intended to represent the generic binary
+ type which has the description:
+ > Generic binary subtype - This is the most commonly used binary subtype and
+ > should be the 'default' for drivers and tools.
+
+ None of these impose any limitations on the internal representation other
+ than the basic unit of storage be some type of array whose parts are
+ decomposable into bytes.
+
+ The default representation of this binary format is a
+ `std::vector<std::uint8_t>`, which is a very common way to represent a byte
+ array in modern C++.
+
+ #### Default type
+
+ The default values for @a BinaryType is `std::vector<std::uint8_t>`
+
+ #### Storage
+
+ Binary Arrays are stored as pointers in a @ref basic_json type. That is,
+ for any access to array values, a pointer of the type `binary_t*` must be
+ dereferenced.
+
+ #### Notes on subtypes
+
+ - CBOR
+ - Binary values are represented as byte strings. No subtypes are
+ supported and will be ignored when CBOR is written.
+ - MessagePack
+ - If a subtype is given and the binary array contains exactly 1, 2, 4, 8,
+ or 16 elements, the fixext family (fixext1, fixext2, fixext4, fixext8)
+ is used. For other sizes, the ext family (ext8, ext16, ext32) is used.
+ The subtype is then added as singed 8-bit integer.
+ - If no subtype is given, the bin family (bin8, bin16, bin32) is used.
+ - BSON
+ - If a subtype is given, it is used and added as unsigned 8-bit integer.
+ - If no subtype is given, the generic binary subtype 0x00 is used.
