Talk:Microsoft Assistance Markup Language
This is out of date - talks about "current type of user assistance" created with hhc.exe. Also mentions Windows Vista, but not Windows 7. Also, what is the support status of MAML? It looks to me like it's going to be replaced - again - with Microsoft Help System.
I hope MS can standardise on something soon... all these changes don't encourage other Windows developers to include good help systems in their products.
