Dear all,

this message is forwarded here FYI. It was originally sent to the  
public list, which I know many of you are not subscribed to. Please  
note that we do not have any form of IP knowledge about this piece of  
technology, so while we can definitely discuss it, if it becomes part  
of our specification we will have to be careful and ask further  
information from Paul Pierce.

> You will find that it is full of invention. While most of the =
> techniques are well known and many are enshrined in existing =
> standards, the proposal rarely makes use of them. For instance, =
> the "Octet" transform is much like X.690 BER and most of the =
> compression is like bzip2 and gzip. I've done this to present =
> alternative techniques that are tuned to XML specific problems =
> and that take advantage of the specific opportunities that =
> arise, such as (in compression) working on whole symbols for =
> speed, instead of bytes. Otherwise I've tried to avoid invention =
> for its own sake, especially avoiding new data structures that =
> would unnecessarily expose the inner workings of a particular =
> translation mechanism and so fix them into the standard where =
> they might limit future innovation.
> I am a retired systems software architect. I worked at Intel =

> of standards committees. Now I have my own projects, many of =
> which use XML. Most don't need binary, but 4 or so are much =
> like different use cases documented in the Binary Characteristics =
> report.
> My understanding of compression techniques comes mostly from =

> Attached is the proposal only. I'll follow up with a brief =
