Prior-Art Related to SGML used for controlling communications structures

[Joseph M. Reagle Jr.]

The W3C is surveying potential prior art to assess the claims of Patent
Number: 5862325. At their Web site Intermind states:
 
   How do I know if I might infringe? 
 
   Products that incorporate Intermind’s technology are fairly easy to
recognize: 
   among other features, they rely on the exchange between publishers and 
   subscribers of a file containing metadata (such as an XML file) to set up 
   an active communications link. We call this file the communications
object.

If you are familiar with any SGML applications that were used to control or
structure the exchange of information over a network, please have a look at
the brief description and let us know! [1]
