Microsoft tried sharing source code to end a European antitrust spat, but that didn't work. Now it's sharing legal filings as well.

Today the company posted on its Web site the 78-page filing it submitted to the European Commission last week.

The filing is Microsoft's response to the commission's December 2005 statement that the company is failing to comply fully with a 2004 ruling against the company.

A sticking point is whether Microsoft has adequately documented the technical information it's required to share with rivals. Microsoft is also posting the reports of several software system engineering professors who reviewed the documentation.
