XML Schema generation by machine learning from a corpus of XMLinstance d

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

Hi Folks,

Scenario: A bunch of XML instance documents are fed into a machine learning program. The program analyzes the instances to learn the structure of the items, which items are mandatory, and which items are optional. Out pops an XML Schema.

Question: Has anyone created an XML Schema generating machine learning program?
