Half-right, half-wrong :)

In the case I quote, yes indeed in order to produce the binary infoset 
corresponding to the description made in the article one would need to have 
access to type information. Note that I was only providing an interpretation of 
the text in the article, sorry if it was insufficiently detailed.

My vision of binary infosets includes using as much metadata as possible to 
obtain more efficient compression. In the presence of a PSVI, the product I work 
on will make use of the typing metadata to better encode its content. In the 
presence of a vanilla XML Infoset, it'll encode it as such. In other words, the 
tool is open to what you want to do with it.

You will certainly have followed this permathread long enough to notice that 
I've stated a dozen times that "Binary XML" and all variations on it are 
language abuses and that "Binary Infosets" is imho much more appropriate. The 
PSVI is one kind of Infoset.
