This makes sense. I still wonder how we can know which text node is being
edited. Any ideas?
Also, where do the views access the DOM and where does the document update the
views? I also think all this needs to be in a Document class so that it makes
sense when one is just exploring the source code.

Subject: [brailleblaster] Dynamic translation
As I see it dynamic or on-the-fly translation will apply to the text node
courrently being edited. Each time a character key is pressed a new
liblouisutdml function will be called to trranslate the node.
liblouisuteml is needed because we are working with an xml document and the
configuration parameters used for the original rendering should be applied. The
function will not be diffiecult to implement. It might be called something like
translateTextNode . There should be no noticeable performance lag for text
nodes of reasonable size. However, I have seen some with tens of thousands of
characters, so dynamic translation may be turned off for such huge nodes.
The dynamic translation may make pagination and other things invalid, so the
user can retranslate (actually, re-render) the documennt.
