6.10 Timely exchanges through APIs

> ACTION: PP to Write up a few examples of situations where an API 
exchange is too slow

Situations in which an API exchange is too slow include, but are not 
limited to, the following:

1. The user agent updates the content in the active view but does not 
indicate the change through the API in a timely manner such that an AT can 
update its cached content before the next user query or command. As a 
result, the user ends up working with stale content.
2. The user agent processes user input but does not indicate confirmation 
through the API in a timely manner such that the user knows the input was 
received. As a result, the user is apt to think the input was lost and 
repeat the action.

Example techniques

1. On Linux, use AT-SPI document events to indicate global changes to a 
document and object events to indicate changes to portions of the content.
