This sounds like you think some other serialization won't have syntactical
nitty-gritty!

If your idea is that the XPath Data Model is an improvement on XML, then
you are lost in the realm of apples and oranges, no slight intended.

Hey, maybe someone should suggest JSON, as the only
programming-language-independent data-oriented serialization format with
traction!

I note that Charles Goldfarb had an inlining model for XML type
information before XSD, in maybe 1997: IIRC it would be (updated with
namespace) something like

 <address city="NY" type:info=". ex:addressType city ex:cityList">
    ...
where there is an added attribute with name/type-name pairs.

And note that ISO NVDL handles disconnected attributes by making a special
dummy element whose semantic is strictly to be a dummy element.
