[macvoiceover] Re: Changing braille tables in documents with Louis

Greg.
I believe your proposed solution would work. It's kind of what I have to do now anyhow, so having to markup the text to get it to translate properly isn't a problem on this end. 
Hope this doesn't throw too large of a wrench in the works.
Hopefully, you've eliminated the 250 entries in the toc problem nfb translater suffered from before I hacked it a bit to behave itself. 
And, the fact that your solution is open source helps too.
My printer needs 27 lines for the first page regardless of what the line count is set for, but all remaining pages work fine, so I've hacked nfbtrans to handle this for me automatically as well. I've also made changes to many of the translation tables (most heavily hit was the back.tab) and created a table for handling artic Technologies book reader format it's book reader uses, so that I can translate these files directly w/o having to translate them back to text first before embossing. A few other modifications, (some of which I don't remember or use anymore) but it's always nice to be able to do so.

We have a request for the ability to change braille tables in documents in Louis. Here is what we are thinking of.
We propose using the XML span tag to do this. You will select the standard braille table in Louis and then should you need to switch into another table you would enclose that section in a span tag. with a single attribute lang indicating the table to switch to. Like this:
<p>This is the text in the normal braille table. <span lang="en-us- g1.ctb">This is in US English grade one.</span> We could also switch languages like going into Swedish braille. <span lang="Se-Se- g1.utbx">Det i svenska</span> And now we would be back to the selected document table.</p> 


Would this work for everyone?
This would work for all XML based documents which is what I highly suggest people use anyway. Louis will attempt to render things like email addresses and URL in computer braille and will switch into nemmeth code braille for MathML which starts and ends with the <math> </math> tags.
