 * {m.n status-data}: the request was understood, and metadata is being returned
 if the reply is {m.n status-data}, the code must be followed by a [!byte-sequence<16>]. the meaning of this sequence is hint-dependent.
 
 
 ## widgets
-the special notation [!tail] refers to the remainder of entry data body, which is wrapped in a sequence header, so the final element does not need an explicit length or termination marker. [!tail<T>] indicates a type [$T] modified such that any length marker for the final value is removed; for instance [!tail<bitmap>] means ([!int<16>:[$pxl-width]] [!tail:[$map]]).
-* {m.n w-paragraph} = [`0x00] [!tail] / shows a block of text
-* {m.n w-section} =  [`0x02] [!tail] / inserts a heading
-* {m.n w-rule} = [`0x07] / inserts a horizontal line that stretches across the screen
-* {m.n w-define} = [`0x03] [!string:[$name]] [!tail:[$val]] / shows a definition (e.g. [`[*Name]: Value]); sequential definitions may be arranged into a table
-* {m.n w-pbar} = [`0x04] [!int<8>:[$progress]] / shows a progress bar; [`0] means empty, [`255] means full
-* {m.n w-bitmap} = [`0x05] [!tail<bitmap>] / shows an image
-* {m.n wi-bitmap} = [`0x06] [!link] [!string] [!tail<bitmap>] / shows an image that can be activated as an option, along with caption that may be displayed in vertical layout or as a substitute for the image in text-only displays
-* {m.n wi-choice} = [`0x01] [!link:[$target]] [!tail:[$label]] / adds an option that can be selected from the menu, causing the client for query for [$target].

 ## roles
 a role is a small piece of metadata that alters the appearance of an object, for example by changing color or applying an icon. defined roles consist of:
