Still the fact remains that XML is nothing but a
different form of comma delimited raw text data. 

It has spawned more software, tools, discussions and
forums on just how to interpret this data. 

The whole concept of writing <xxxxx> followed by
</xxxxx> is almost childlike in its simplicity and
wastefulness. 

Why are someone talking about binary XML suddenly?
