Request: Techniques for reducing the size of XML instances

["Roger L. Costello" <costello@mitre.org>]

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
