Binary XML

Can someone explain to me the idea behind binary XML.

My initial interest in XML was due to the pitfalls of using binary
distributed objects such as COM / CORBA. The protocols worked fine but
had major problems when presented with a firewall and security settings.

I am just interested in how binary XML will circum-navigate all the
security scares that the doom & gloom consultants attach to binary

     Well we've really come full-circle haven't we? :-) The various
minimization features of SGML (SHORTTAG, DATATAG, OMITTAG) would mostly
allow for your first option. You'd need SOME tags, but how many depends

Lots of people are pursuing some form of binary XML. Unfortunately,
else will have to provide the roundup as I don't have a good grip on all
those at the moment.

     This topic comes up occasionally, so you might want to check back
through the archives for threads on compression and such. I recall there
were also some techniques discussed for compression based on lement
patterns or some such thing, very similar to SGML minimization. Hope

Hi Folks,

Does anyone have a summary of techniques for reducing the size of XML
instances (as would be required in limited bandwidth applications)?

XML instance minus tags:

Are there techniques for reducing the size of XML instances by simply
stripping off the tags (thus maintaining an ASCII document)?  [It is not
clear to me how the receiver of such a tagless document would regenerate
the original instance document.]

Binary Compression:

I am sure that there are lots of tools to binary compress XML
instances.  Does anyone have a summary of such tools?  /Roger
