   RE: [xml-dev] Hostility to "binary XML" (was Re: [xml-dev] XML 2004 webl

[ Lists Home | Date Index | Thread Index ]

Would this situation improve if an effort to create a binary 
were prepositioned by an effort to improve/simplify XML?  

I think it time (past time perhaps) to finally cut the cords 
to ISO 8879 and put XML at the top of the stack.  That is 
the reality of the market and the opportunity.  Whereas 
I've always been known to argue this point, it is time I 
admit being wrong.  I'm not one to put a knife in any 
person's back, but this is technology and technology is 
just stuff.  We can improve it and we should because that 
is what we do and the world counts on us to do it.


PS:  Top Impression of XML 2004:  
My lasting impression is of the decency of the XML 
community.  From the leadership to the newest newbie, 
I've never encountered a more good hearted, capable and 
ethical community.  I am humbled and awed.  And glad.

And I know absolutely nothing about ukeleles... "I hope 
I passed the audition."

One can do validation in the writer and then plausibly skip the sort of
checks you mention in a reader, and still be talking about XML, even
with today's textual interchange formats.

Neither am I, which is why W3C has a Working Group to investiate whether
it might be possible, rather than a WG to implement a homunculus :-)
