+1 to automating this. The more the better :-)
There's probably some details to sort out such as wanting to generate
multiple template files from the same schema file where parameters are
optional. Because the generation of the api samples doubles as real
integration testcases which often pick up issues which the normal
unittests don't. But I'd love to see these autogenerated (they are a
bit of pain to create manually).
Longer term I'd like us to think about how we can use the schema
files to automate more of the doc generation too (given full Pecan/WSME
support is likely still a reasonable way off).
