W3C XML Schema was pretty much conceived and designed at the object
model level first, with XML representation added afterwards.

XPath likewise (although you didn't ask about that) -- it was James
Clark's proposal to abstract away from the original concrete syntax of XPath
to the abstract syntax of axes which allowed the XSL and XLink working
groups (proprietors at the time of XPath and XPointer respectively) to
agree on a common framework.
