schema.org xsd ??

Greetings

We are working with OAI transmission and are thinking about using schema.org
vocabulary parts in both harvesting and transmitting. The OAI specification
dictates XML usage. We want to validate files we harvest. I'm wondering if
anyone has crafted a xsd file to validate some or all of schema.org terms.
Does anyone know of any files in the wild or have a way to convert the
linked data files to an xsd file for validation?


all the best,
