Perhaps. It seems you're arguing (and please correct me if I'm wrong) 
for a binxml that has more information than a plain vanilla XML 
document. Your vision of binxml includes type information. That is, 
it knows what's a string and what's an int and what's a date and 
what's binary data and so forth. Is that accurate?

If so, it seems that your BinXML is really not BinXML at all. Rather 
it's a BinPSVI or something like that. There's more information in a 
BinXML document than there is in the equivalent XML document. You 
have tag names, content, attributes, and types. XML only has tag 
names, content, attributes. No types.
