Using Set Operations to Create Powerful New XML Languages

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

Hi Folks,

I wrote a short paper that shows how to create powerful new XML languages by applying set operations to existing XML languages.

The technique shown in the paper is quite different from approaches employed today, which create new XML languages by extending or restricting an XML Schema. The approach employed today is grammar-based whereas the technique shown in this paper is set-based. Sets are the foundation of mathematics, so by using set operations to create new XML languages we have at our disposal the entire power of mathematics!

Here is the paper:

Comments welcome.

Many thanks to Rick Jelliffe for his insights on intersecting XML languages.
