"This paper proposes extending popular object-oriented programming languages such as C#, VB or Java with native support for XML. In our approach XML documents or document fragments become first class citizens. This means that XML values can be constructed, loaded, passed, transformed and updated in a type-safe manner. The type system extensions, however, are not based on XML Schemas. We show that XSDs and the XML data model do not fit well with the class-based nominal type system and object graph representation of our target languages. Instead we propose to extend the C# type system with new structural types that model XSD sequences, choices, and all-groups. We also propose a number of extensions to the language itself that incorporate a simple but expressive query language that is influenced by XPath and SQL. We demonstrate our language and type system by translating a selection of the XQuery use cases."

I talk to Erik about this stuff all the time, so it's great to finally see some of the thoughts and discussions around this topic actually written down in a research paper. According to Erik's blog post from a few weeks ago he'll actually be presenting about this at XML 2003

And we end up with yet another schema format, yet another query language, etc. I suppose this is unavoidable if the existing specifications don't work. Is this likely to affect the use of those specifications, especially for the programmers that don't use an xmlized programming language, or are all of these specifications going to co-exist peacefully (hahaha)?
