It depends.  I suggest not to get concentrated  on the particular 
"cell-phone", but to think about 'some device with low memory'.

Before we got PC - many things ( like compilers, OS e t.c) 
were already in place on big computers.  Then PC appears - 
and we need to calculate memory and use  assembly again.
OK, we have PC. Everything is fine, memory is cheap after 
a years of progress we have UNIX running on PC. Then we got, 
for example,  VeriPhone POS ( to process credit cards ) - and 
we are again in the world of low-level programming with limited 
resources e t.c. 

I think this is endless process, because it was endless before.

Maybe something very important happened and now there is some 
way to be more happy about the future? I don't think so.

But there will always be some device with limited resources.
I don't know why it always happens that programms need 
more resources than hardware could give and I don't 
understand why it should change. I don't know why 
Java VM is not already embedded into every device. 

Maybe hardware vendors have some reason for it ?

Not talking about the history of  Next computer ...  wasn't it 
perfect? ... but too expensive .... I think the same is with any 
hardware, including cell-phone. So there will be for sure 
some cell-phones not running ECMAScript interpreter.

The question is what framework would fit  better into 
'cell-phone'  - XML-based or SML-based. 

I think that because people from that hardware world 
are already implementing the subsets of XML - it 
should be taken into account.

Actualy, getting SML in place may help  *XML*  to get 
better market share.  SML could be kind of  
XML for very-very-very thin clients ;-)

Alfred parser showed that XML parser could be small.
Unfortunately,  *only*  the parser may be not enough.  

I want  XT to run everywhere ;-)
