Data Model Xsd or other schema document

[EJ Alexandra]

Is there a formal (central) Xsd for the freshbook api schema?  Basically, there's an XML input and output (request/response) for each API method - but is there one, central version of this xml?  I could "scrape" it from the docs I guess - but it seems like it would be easier if one is just available publicly.

To be clear - I'm not really looking for anything other than a more machine readable way to process the request/response xml blobs for the whole api.

Thanks.
