 **Hardware keyboard:** an input device which has individual keys that are pressed. Each key has a unique identifier and the arrangement doesn't change, even if the mapping of those keys does. Also known as a physical keyboard.

 **Input Method Editor (IME):** a component or program that supports input of large character sets. Typically, IMEs employ contextual logic and candidate UI to identify the Unicode characters intended by the user.
 
-<!-- **ISO position:** The corresponding position of a key using the ISO layout convention where rows are identified by letters and columns are identified by numbers. For example, "D01" corresponds to the "Q" key on a US keyboard. For the purposes of this document, an ISO layout position is depicted by a one-letter row identifier followed by a two digit column number (like "B03", "E12" or "C00"). The following diagram depicts a typical US keyboard layout superimposed with the ISO layout indicators (it is important to note that the number of keys and their physical placement relative to each-other in this diagram is irrelevant, rather what is important is their logical placement using the ISO convention):

-One may also extend the notion of the ISO layout to support keys that don't map directly to the diagram above (such as the Android device - see diagram). Per the ISO standard, the space bar is mapped to "A03", so the period and comma keys are mapped to "A02" and "A04" respectively based on their relative position to the space bar. Also note that the "E" row does not exist on the Android keyboard.

-If it becomes necessary in the future, the format could extend the ISO layout to support keys that are located to the left of the "00" column by using negative column numbers "-01", "-02" and so on, or 100's complement "99", "98",… -->

 **Keyboard implementation:** Software which implements the present specification, such that keyboard XML files can be used to interpret keystrokes from a **Hardware keyboard** or an on-screen **Touch keyboard**.
 
 Keyboard implementations will typically consist of two parts:
