Using any client API, how to set XmlDocuments on content type?

[Steve Beaugé]

Hello,

I'm trying to feed the XmlDocuments of content types using any client API.

I didn't find anything that can set these documents neither:

• in CSOM
• nor in REST API
• nor in any webservice

Using server side object model, I can simply manipulate SPContentType.XmlDocuments collection.

Thanks
