Jonathan Robie announced the first public draft of the XML Query Data Model.
Of the document, the first formal deliverable beyond requirements,
Robie said:
"I think that this document illustrates how formal notation can increase
precision and clarity while reducing the complexity of a spec."
The data model proposed supports schema types (though not yet keys and key references), references (idrefs and
perhaps XLink?), namespaces, and collections of documents (rather than just single documents), as well as the XML features
identified by the XML Infoset.
