Subject: Re: [emergency-msg] Backward compatibility


Ah! Thanks for the clarification, Art,

I was a bit confused but the connection has now been made and I agree 
with you. Partly my confusion was due to the fact that I am about to 
venture into VoiceXML waters, where, as it turns out, v2.0 which is 
what most everyone is using or preparing to switch to imminently, is 
not backwardly compatible with v1.0 and we just had a rather lengthy 
discussion in another venue about whether to consider compatibility 
with 1.0 and decided against it. Generally, this is something I am 
rather vehemently against, but I was convinced due in no small part 
to my own ignorance of said subject as I try to get up to speed on 
it, AND not having to learn v1.0 was the path of least resistance. 
That's not a good argument for such a practice, and I don't recommend 
it. I just admit to it. I was also overruled on a number of issues. 
However, I mention all this because I'm getting my feet wet these 
waters largely because of my participation in Web Services for Remote 
Portlets TC, where I somehow volunteered to chair the markup 
subcommittee. It strikes me as a very likely that VoiceXML for ICS 
Forms via telephonic devices on the fly will rear its head all too 
soon. Eventually, I'm sure we will also see voice activated 
pda/notebook type mobile and/or handheld devices that we will want to 
use effectively in EM, and while we are looking at infrastructure and 
versioning issues, we might as well start thinking about these 
things, too.

Ciao,
Rex
