The XML "API" is flexible because of its simplicity: it returns a string
containing a serialized tree of nodes, each of which has:

1) A name (== type)
2) Zero or more key-value parameter pairs
3) Zero or more children (which can be either nodes or text)

Perhaps we can simplify the C AST API to return an iterator over such a
tree? Then it's infinitely flexible, just like the XML "API". We can add
types, remove types, add parameters, remove parameters, etc. at any time,
maintaining binary compatibility.
