+// Package document provides interface definitions and error types for document types.
+//
+// A document is a protocol-agnostic type which supports a JSON-like data-model. You can use this type to send
+// UTF-8 strings, arbitrary precision numbers, booleans, nulls, a list of these values, and a map of UTF-8
+// strings to these values.
+//
+// API Clients expose document constructors in their respective client document packages which must be used to
+// Marshal and Unmarshal Go types to and from their respective protocol representations.
+//
+// See the Marshaler and Unmarshaler type documentation for more details on how to Go types can be converted to and from
+// document types.

+// Marshaler is an interface for a type that marshals a document to its protocol-specific byte representation and
+// returns the resulting bytes. A non-nil error will be returned if an error is encountered during marshaling.
+//
+// Marshal supports basic scalars (int,uint,float,bool,string), big.Int, and big.Float, maps, slices, and structs.
+// Anonymous nested types are flattened based on Go anonymous type visibility.
+//
+// When defining struct types. the `document` struct tag can be used to control how the value will be
+// marshaled into the resulting protocol document.

+//		// Field is ignored
+//		Field int `document:"-"`
+//
+//		// Field object of key "myName"
+//		Field int `document:"myName"`
+//
+//		// Field object key of key "myName", and
+//		// Field is omitted if the field is a zero value for the type.
+//		Field int `document:"myName,omitempty"`
+//
+//		// Field object key of "Field", and
+//		// Field is omitted if the field is a zero value for the type.
+//		Field int `document:",omitempty"`
+//
+// All struct fields, including anonymous fields, are marshaled unless the
+// any of the following conditions are meet.
+//
+//		- the field is not exported
+//		- document field tag is "-"
+//		- document field tag specifies "omitempty", and is a zero value.
+//
+// Pointer and interface values are encoded as the value pointed to or
+// contained in the interface. A nil value encodes as a null
+// value unless `omitempty` struct tag is provided.
+//
+// Channel, complex, and function values are not encoded and will be skipped
+// when walking the value to be marshaled.
+//
+// time.Time is not supported and will cause the Marshaler to return an error. These values should be represented
+// by your application as a string or numerical representation.
+//
+// Errors that occur when marshaling will stop the marshaler, and return the error.

+// Unmarshaler supports the same encodings produced by a document Marshaler. This includes support for the `document`
+// struct field tag for controlling how struct fields are unmarshaled.
+//
